Answers & Solutions:<\/strong><\/span><\/p>\n

1)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

As we know, formulae of compound interest for 2 years \u00a0will be:
\n$P(1+\\frac{r}{100})^{2}$ = 625\u00a0 (Where r is rate, P is principal amount)
\nFor 3 years:
\n$P(1+\\frac{r}{100})^{3}$ = 675
\nDividing above two equations we will get r=8%<\/p>\n

2)\u00a0Answer\u00a0(A)<\/strong><\/p>\n

For the first year, interest= 1200000*0.08<\/p>\n

It has been given that she repays the principal of the loan in 25 years i.e she pays\u00a0$\\frac{1200000}{25}$ = Rs 48000 at the end of every year.<\/p>\n

Therefore the interest for the second year is calculated only on the remaining sum i.e 1200000-48000 = Rs 1152000<\/p>\n

for the second year, interest\u00a0 = 1152000*0.08<\/p>\n

On similar lines for the twenty-fifth year = 48000*0.08<\/p>\n

This is in AP with first term 48000*0.08 with common difference 3840<\/p>\n

Total interest =\u00a0$\\ \\frac{\\ 25}{2}\\left(2\\times\\ 48000\\cdot0.08+24\\cdot3840\\right)$<\/p>\n

=1248000<\/p>\n

A is the correct answer.<\/p>\n

3)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

Let the principal amount = $P$ and rate of interest = $r \\%$<\/p>\n

Interest accumulated from 2004 to 2007 is Rs.10,000 and from 2004 to 2010 is Rs.25,000<\/p>\n

Using, $C.I. = P[(1 + \\frac{R}{100})^T – 1]$<\/p>\n

=> $P[(1 + \\frac{r}{100})^3 – 1] = 10,000$ ———-Eqn(I)<\/p>\n

and $P[(1 + \\frac{r}{100})^6 – 1] = 25,000$ ———–Eqn(II)<\/p>\n

Dividing eqn(II) from (I), we get\u00a0:<\/p>\n

=> $\\frac{P[(1 + \\frac{r}{100})^6 – 1]}{P[(1 + \\frac{r}{100})^3 – 1]} = \\frac{5}{2}$<\/p>\n

Let $(1 + \\frac{r}{100})^3 = x$<\/p>\n

=> $\\frac{x^2 – 1}{x – 1} = \\frac{5}{2}$<\/p>\n

=> $2x^2 – 5x + 3 = 0$<\/p>\n

=> $(2x – 3) (x – 1) = 0$<\/p>\n

=> $x = \\frac{3}{2} , 1$ \u00a0 \u00a0$(x \\neq 1)$ because then, r = 0<\/p>\n

=> $(1 + \\frac{r}{100})^3 = \\frac{3}{2}$<\/p>\n

Substituting it in eqn(I)<\/p>\n

=> $P[\\frac{3}{2} – 1] = 10,000$<\/p>\n

=> $P = 10,000 \\times 2 = 20,000$<\/p>\n

4)\u00a0Answer:\u00a020920<\/b><\/p>\n

The amount with Amal at the end of 1 year = 12000*1.08+10000*1.03*1.03=23569<\/p>\n

Interest received by Amal = 23569-22000=1569<\/p>\n

Let the amount invested by Bimal = 100b<\/p>\n

Interest received by Bimal = 100b*7.5*1\/100=7.5b<\/p>\n

It is given that the amount of interest received by both of them is the same<\/p>\n

7.5b=1569<\/p>\n

b=209.2<\/p>\n

Amount invested by Bimal = 100b = 20920<\/p>\n

5)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

Let the interest on the second part be $r$ %
\nThen, the rate on the first part = ($r$ + 10)%It is given that,
\n$30000(1 + \\dfrac{r + 10}{100})^2 – 30000(1 + \\dfrac{r}{100})^2 = 7500$
\nOn solving, we get $r$ = 20%
\nLet the first part be Rs. $a$
\nThen, the second part = Rs. (60000 – $a$)
\n$a(1 + \\dfrac{20 + 10}{100})^2 – (60000 – a)(1 + \\dfrac{20}{100})^2$ = 38800
\nOn solving, we get $a$ = Rs. 40000<\/p>\n

Hence, option C is the correct answer.<\/p>\n\n

6)\u00a0Answer\u00a0(A)<\/strong><\/p>\n

Simple Interest =\u00a0$\\ \\frac{\\ P\\cdot T\\cdot r}{100}$ where P is the principal, T is the time period and r is the rate of interest.<\/p>\n

The simple interest accrued on a sum of certain principal in 8 years at the rate of 13% per year is Rs.6500<\/p>\n

6500=$\\ \\frac{\\ P\\times\\ 8\\times\\ 13}{100}$<\/p>\n

P = Rs. 6250<\/p>\n

Compound Interest on 6250 for 2 years at 8% rate of interest = 6250$\\left(1+\\ \\frac{\\ 8}{100}\\right)^2$- 6250<\/p>\n

= Rs. 1040<\/p>\n

A is the correct answer.<\/p>\n

7)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

Let the amount invested in X = x
\nThus, the amount invested in Y = 25000-x
\nThe interest incurred = 3518 Rs, thus the total amount at the end of the 2nd year = 28518 Rs.
\nThus, $x*(1.06)^2 + (25000-x)*(1.08)^2 = 28518$
\n=> $x*1.1236 + 25000*1.11664 – x*1.11664 = 28518$
\n=> $-0.0428x + 29160 = 28518$
\n=> $ 642 = 0.0428x$
\nHence, $x = 15000 Rs$
\nHence, option C is the correct answer.<\/p>\n

8)\u00a0Answer\u00a0(E)<\/strong><\/p>\n

Rs. 15 lakhs is to be divided equally.<\/p>\n

In the case of the younger son,
\nPrincipal = Rs. 750000, time = 9 years and Interest = Rs. 1350000
\nRate of interest = $\\dfrac{1350000 * 100}{750000 * 9}$ = 20%<\/p>\n

In the case of the elder son,
\nPrincipal = Rs. 750000, time = 6 years and Interest = Rs. 1350000
\nRate of interest = $\\dfrac{1350000 * 100}{750000 * 6}$ = 30%<\/p>\n

Hence, option E is the correct answer.<\/p>\n

9)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

Hi total gain = 5%
\nThus, the amount at the end of 3 years = 105 lakh Rupees
\nThe amount he gets from the bank = $30(1.12)^3 = 42.14784$ lakh rupees
\nLet x be the percentage at which he sells the assets of worth 70 lakhs
\nThus, the amount he gets = 0.7x lakhs
\nThus, 70x + 42.1478 = 105
\nThus, 70x = 62.8525
\nThus, x is closest to 0.90= 90%
\nHence, option C is the correct answer.<\/p>\n

10)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

The sum that was returned is same in both cases that means interest accrued is same in both cases.<\/p>\n

Assume that the duration is ‘t’ years for which amount is borrowed in both case and principal amount is ‘P’.<\/p>\n

$\\frac{P*(t-0.5)*10} {100}$ =\u00a0$\\frac{P*t*8} {100}$<\/p>\n

t=2.5 years<\/p>\n

Principal amount that the enterprise borrowed :<\/p>\n

$P(1+\\frac{2*10}{100})$ =62100<\/p>\n

P=51750<\/p>\n
