Solutions for CAT Questions on Installments:

Solutions:

1) Answer (A)

Let the installment paid be x.
The amount 150000 earns an interest for 3 years. So, the installments must also compensate for the interest.
The first installment paid will earn an interest for 2 more years, the second installment paid will earn an interest for 1 more year and the last installment paid will earn not earn any interest.
=> $150000(1.2)^3 = x(1.2)^2 + x(1.2) + x$
=> $150000(1.2)^3 = 3.64x$
=> x = Rs 71209

2) Answer (C)

Since there is a disount of 8% and a cash down payment of Rs 50000,
Effective price on which installments begin=92%ofRs5lakhs-Rs50000=Rs410000
Let the yearly installments be x
After one year,amount remaining after paying 1st installment= 1.2(410000)-x
After two years,amount remaining after paying 2nd installment=(1.2(1.2(410000)-x)-x)
Similarly after 3 years amount remaining=1.2(1.2(1.2(410000)-x)-x)-x=0
x=Rs 194637

3) Answer (C)

Let the value of the installments Raj paid be x.
Total amount after 2 years = $18900 [1 + 0.1]^2$
He pays the first installment at the end of the first year and the second at the end of the second year.
Therefore,
$18900 [1 + 0.1]^2$ = $x [1 + 0.1] + x$
18900 * 1.21 = 2.1x
x = 10890

4) Answer (B)

In Scheme 1 the washing machine will be sold at 20% discount, that is, for Rs. 12000.
The money earned by Slipkart at the end of three years is
$=12000\times(1.1)^{3}=15972$
In Scheme 2 Slipkart earns interest on 5000 for 3 years, 3000 for 2 years, 3000 for 1 year and no interest on the final 3000.
The money earned by Slipkart at the end of three years is
$=5000\times(1.1)^{3}+3000\times(1.1)^{2}+3000\times(1.1)+3000=16585$
So Slipkart earns Rs. 613 more in Scheme 2.

5) Answer (C)

Rs 5000 at the end of three years amounts to
$5000*(1+4/100)^6$ = Rs 6326.6
Rs 1000 is paid at the end of the first year.
Interest incurred on this payment at the end of the 3 years = $1000*(1+4/100)^4$ = Rs 1169.9
Another installment of Rs 1000 is paid at the end of the second year
Interest incurred on this payment at the end of the 3 years = $1000*(1+4/100)^2$ = Rs 1081.6
So, amount that has to be paid at the end of the third year = 6326.6 – (1169.9 + 1081.6) = Rs 4075.1
So, amount that has to be paid at the end of the third year so as to clear all dues = Rs 4075.1
