Question : Z is increased successively by $11 \frac{1}{9}$% and 10% to get R. If R = 165, then what is the value of Z?
Option 1: 145
Option 2: 115
Option 3: 125
Option 4: 135
Correct Answer: 135
Solution : Increase = $11 \frac{1}{9}$% and 10% Net increase = $\frac{100}{9} + 10 + \frac{100}{9}×\frac{10}{100}$ = $\frac{200}{9}$% R = 165 So, Z + $\frac{200}{9}$% of Z = 165 ⇒ $\frac{11}{9}$ × Z = 165 ⇒ Z = $\frac{165×9}{11}$ = 15 × 9 = 135 Hence, the
Question : The cost price of a notebook is INR 120. It is sold at a profit of 40%. What is the nominal profit made on the sale of each notebook?
Option 1: INR 36
Option 2: INR 48
Option 3: INR 24
Option 4: INR 40
Correct Answer: INR 48
Solution : Cost price of a notebook = INR 120 Profit percentage = 40% Selling price = $\frac{100 + \text{Profit percentage}}{100}\times$ Cost price = $\frac{100+40}{100}\times120$ = $\frac{140}{100}\times120$ = INR 168 Nominal profit made on the sale of each notebook = Selling Price – Cost Price So,

Question : If $A=\frac{2}{3} \div \frac{4}{9}, B=\frac{6}{11} \times\frac{33}{12}$ and $C=\frac{1}{3} \times \frac{9}{2}$, then what is the value of $A \times B-C$?
Option 1: $\frac{3}{8}$
Option 2: $\frac{3}{2}$
Option 3: $\frac{3}{4}$
Option 4: $\frac{3}{16}$
Correct Answer: $\frac{3}{4}$
Solution : $A=\frac{2}{3} \div \frac{4}{9}=\frac{2}{3} \times \frac{9}{4}=\frac{3}{2}$ $B=\frac{6}{11} \times\frac{33}{12}=\frac{3}{2}$ $C=\frac{1}{3} \times \frac{9}{2}=\frac{3}{2}$ $\therefore A \times B-C$ $=\frac{3}{2}\times\frac{3}{2}-\frac{3}{2}$ $=\frac{9}{4}-\frac{3}{2}$ $=\frac{9-6}{4}$ $=\frac{3}{4}$ Hence, the correct answer is $\frac{3}{4}$.
