Answers & Solutions:

1) Answer (D)

$\frac{5}{8} \times \frac{13}{5} \div \frac{4}{9} = \frac{13}{8} \times \frac{9}{4}$

This equals $\frac{117}{32} = 3\frac{21}{32}$

2) Answer (C)

$10.8 \times 5.5 \times 8.4 = 59.4 \times 8.4$

This equals $59.4 \times 8.4 = 498.86$

3) Answer (D)

According to the BODMAS rule, division should be solved before subtraction.

Hence, the simplification of the expression is $45 \div 5 – 0.5 = 9 – 0.5 = 8.5 $

Hence, the correct option is option (d)

4) Answer (E)

According to the BODMAS rule, the expression in the bracket should be solved first.

Hence, the simplification of the expression is $3.5 \times (60 \div 2.5) = 3.5 \times 24$

$3.5 \times 24 = 84$

5) Answer (A)

The simplified expression equals $(4\times4\times4\times4\times4\times4)^{5}\times(4\times4\times4)^{8}\div(4)^{3}= (4^6)^5 \times (4^3)^8 \div 4^3 = 4^{30} \times 4^{24} \div 4^3 = 4^{30+24-3} = 4^{51}$

$64 = 4^3$

So, $4^{51} = 4^{3 \times 17} = (4^3)^{17} = 64^{17}$

Hence the correct answer is 17

6) Answer (B)

Let the number in question mark be equal to ‘$x$’

So, $5 \times x = 8484 \div 4$

So, $5 \times x = 2121 $

So, $x = \frac{2121}{5} = 424.2$

7) Answer (E)

Let the number used in place of the question mark be equal to ‘$x$’

So, $7059 – 2350 + 1936 = x \times 50$

So, $6645 = x \times 50$

So, $x = \frac{6645}{50} = 132.9$

8) Answer (C)

Let the number in question mark be equal to ‘$x$’

So, 16% of 550 $\div x$ % of 500 = 2.5

So, 88 $\div x$% of 500 = 2.5

So, $x$% of 500 = 88 $\div$ 2.5

Or, $x$ = 35.2 $\div$ 5 = 7.04

9) Answer (E)

Let the number in question mark be equal to ‘$x$’

So, $8648 – 7652 = x \times 40$

Or, $996 = x \times 40$

Or, $x = 996 \div 40 =24.9$

As this is not present in the options given, the correct answer is (d)

10) Answer (B)

Let the number to be used in the place of the question mark be equal to ‘$x$’

So, 22% of 364 – $x$ = 23

Or, 80.08 – $x$ = 23

So, $x$ = 80.08 – 23 = 57.08

11) Answer (A)

The expression when simplified becomes

683.46 – 227.39 – 341.85 = 456.07 – 341.85 = 114.22

12) Answer (C)

The expression when simplified becomes

$3\frac{2}{3}+2\frac{3}{4}+1\frac{1}{2} = \frac{11}{3} + \frac{11}{4} + \frac{3}{2}$

This equals $\frac{44}{12} +\frac{33}{12} + \frac{18}{12} = \frac{95}{12}$

Hence, it equals $7\frac{11}{12}$

13) Answer (B)

Let the number to be used in place of the question mark be equal to ‘$x$’

Hence, $\sqrt{x} – 5 = \sqrt{2209}$

$\sqrt{2209} = 47$

So, $\sqrt{x} – 5 = 47$

So, $\sqrt{x} = 52$

Hence, $x = 52^2$

14) Answer (A)

14.5 % of 608 = 14.5/100 * 608

This equals 8816/100 = 88.16

15) Answer (D)

In equations with more than one division sign, we solve the divisions from the left first.

In this case, $840 \div 40 \div 0.5 = 21 \div 0.5 = 42$
