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

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

Expression\u00a0:\u00a0(0.7 \u00d7 0.7 \u00d7 0.7 – 0.6 \u00d7 0.6 \u00d7 0.6) \u00f7 (0.7 \u00d7 0.7 + 0.6 \u00d7 0.6 + 0.7 \u00d7 0.6)<\/p>\n

Substituting 0.7 with a and 0.6 with b, we get\u00a0:<\/p>\n

= $\\frac{a^3 – b^3}{a^2 + b^2 + ab}$<\/p>\n

Using, $(x^3 – y^3) = (x – y) (x^2 + y^2 + xy)$<\/p>\n

= $\\frac{(a – b) (a^2 + b^2 + ab)}{(a^2 + b^2 + ab)}$<\/p>\n

= $a – b = 0.7 – 0.6$<\/p>\n

= $0.1$<\/p>\n

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

By adding we get 2278.235+21.2323=2299.4673
\nHence, option A\u00a0is the correct answer.<\/p>\n

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

Given\u00a0:\u00a0$(\\frac{1}{5})^{3y}=0.008$<\/p>\n

=>\u00a0$(\\frac{1}{5})^{3y}=\\frac{8}{1000}=\\frac{1}{125}$<\/p>\n

=>\u00a0$(\\frac{1}{5})^{3y}=(\\frac{1}{5})^3$<\/p>\n

=> $3y=3$<\/p>\n

=> $y=\\frac{3}{3}=1$<\/p>\n

$\\therefore$\u00a0$(0.25)^{y}=(0.25)^1=0.25$<\/p>\n

=> Ans –\u00a0(A)<\/p>\n

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

Given\u00a0:\u00a0$\\ x^{3}=1.5^{3} – 0.9^{3}-2.43$<\/p>\n

= $(1.5)^3-(0.9)^3-3\\times1.5\\times0.9\\times0.6$<\/p>\n

= $(1.5)^3-(0.9)^3-3(1.5)(0.9)(1.5-0.9)$<\/p>\n

= $(1.5-0.9)^3=(0.6)^3$<\/p>\n

=> $x=0.6$<\/p>\n

=> Ans – (B)<\/p>\n

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

By adding we get 986.834+631.279=1618.113
\nHence, option D is the correct answer.<\/p>\n

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

By adding we get 1654.664+72.326=1726.99
\nHence, option B is the correct answer.<\/p>\n

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

By simplification we get
\n=(2\/3)*(8\/10)*900
\n=480
\nHence, option B is the correct answer.<\/p>\n

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

By Applying BODMAS we have 47*21\/120
\n=47*7\/40
\n=329\/40
\n=8.225<\/p>\n

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

=$5 – 6.5 \\div 13 + 2.3 \\times 0.8 + 0.4$
\n=$5 – 0.5 + 2.3 \\times 0.8 + 0.4$
\n=$5 – 0.5 + 1.84 + 0.4$
\n=$4.5 1.84 + 0.4$
\n=6.74<\/p>\n

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

Expression\u00a0:\u00a0$16.02^{2} + 144 + 23.96 + ? = 783.867$<\/p>\n

=> $16^2 + 144 + 24 + x = 784$<\/p>\n

=> $256 + 168 + x = 784$<\/p>\n

=> $x = 784 – 424 = 360$<\/p>\n

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

Expression\u00a0:\u00a0$(\\frac{42.25}{0.5}+\\frac{16.2}{0.2})\\times?=1986$<\/p>\n

=> $(84.5 + 81) \\times x = 1986$<\/p>\n

=> $165.5 \\times x = 1986$<\/p>\n

=> $x = \\frac{1986}{165.5} = 12$<\/p>\n

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

Expression\u00a0:\u00a0$\\frac{1.12 \\times 2.24 – 0.78 \\times 1.56}{4 \\times (1.12 – 0.78)} = ?$<\/p>\n

= $\\frac{2 (1.12)^2 – 2 (0.78)^2}{4 (1.12 – 0.78)}$<\/p>\n

= $\\frac{2 (1.12 – 0.78) (1.12 + 0.78)}{4 (1.12 – 0.78)}$ \u00a0 \u00a0 [Using, $a^2 – b^2 = (a – b) (a + b)$]<\/p>\n

= $\\frac{1.12 + 0.78}{2}$<\/p>\n

= $\\frac{1.9}{2} = 0.95$<\/p>\n

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

Expression\u00a0:\u00a07831.63 + 2593.59 + 194.67 – 5452.21 = ?<\/p>\n

=\u00a010619.89 – 5452.21<\/p>\n

=\u00a05167.68<\/p>\n

14)\u00a0Answer\u00a0(D)<\/strong><\/p>\n

$\\large\\frac{1}{11}$ $=$ $9.09$%<\/p>\n

$\\Rightarrow$ $\\large\\frac{3}{11}$ $=$ $27.27$%<\/p>\n

$27.27$% of $2112$ $=$ $\\large\\frac{3}{11}$ $\\times2112$ $=$ $576$<\/p>\n

$\\large\\frac{1}{9}$ $=$ $11.11$%<\/p>\n

$\\large\\frac{5}{9}$ $=$ $55.55$%<\/p>\n

$55.55$% of $3276$ $=$ $\\large\\frac{5}{9}$ $\\times3276$ $=$ $1820$<\/p>\n

$\\large\\frac{1}{30}$ $=$ $3.33$%<\/p>\n

$\\large\\frac{7}{30}$ $=$ $23.33$%<\/p>\n

$23.33$% of $1950$ = $\\large\\frac{7}{30}$ $\\times1950$ $=$ $455$<\/p>\n

$27.27$% of $2112$ $+$ $55.55$% of $3276$ $-$ $23.33$% of $1950$ $=$ $576$ $+$ $1820$ $-$ $455$ $=$ $1941$<\/p>\n

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

The given expression is:-
\n$(15.012)^3 – (55.072)^2 + 88$% of $999.989 = ?$
\nIt can be approximated as:-
\n$(15)^3 – (55)^2 + 88$% of $1000 = ?$
\n$3375 – 3025 + 880 = ?$
\nThus, ? =1230.
\nHence, option B is the correct answer.<\/p>\n\n
