Question : What is the value of $\frac{\left(\frac{28}{9} \times \frac{42}{35}\right) \div\left(\frac{3}{25} \times \frac{5}{7} \div \frac{1}{21}\right)}{\left(\frac{14}{15} \div \frac{2}{75} \text { of } \frac{7}{5}\right) \times \frac{1}{75} \div \frac{4}{3}} ?$
Option 1: $\frac{222}{27}$
Option 2: $\frac{212}{27}$
Option 3: $\frac{244}{27}$
Option 4: $\frac{224}{27}$
Correct Answer: $\frac{224}{27}$
Solution : $\frac{(\frac{28}{9} \times \frac{42}{35}) \div(\frac{3}{25} \times \frac{5}{7} \div \frac{1}{21})}{(\frac{14}{15} \div \frac{2}{75} \text { of }\frac{7}{5}) \times \frac{1}{75} \div \frac{4}{3}}$ = $\frac{(\frac{4}{3}×\frac{14}{5})÷(\frac{3}{25}×\frac{5}{7}×21)}{(\frac{14}{15}÷\frac{14}{375})×\frac{1}{75}×\frac{3}{4}}$ = $\frac{(\frac{4}{3}×\frac{14}{5})÷(\frac{3}{5}×3)}{(\frac{14}{15}×\frac{375}{14})×\frac{1}{75}×\frac{3}{4}}$ = $\frac{\frac{4}{3}×\frac{14}{5}×\frac{5}{9}}{25×\frac{1}{75}×\frac{3}{4}}$ = $\frac{56}{27}×4$ = $\frac{224}{27}$ Hence, the correct answer is $\frac{224}{27}$.
Question : A sum of INR 900 is divided into two parts such that the interest on the first part at 4% simple interest per annum and that on the other part at 2% simple interest per annum are equal. What is the interest accumulated on each part in a year?
Option 1: INR 18
Option 2: INR 6
Option 3: INR 12
Option 4: INR 20
Correct Answer: INR 12
Solution : Total sum, $P$ = INR 900 The interest rate on the first part, $R_1$ = 4% The interest rate on the second part, $R_2$ = 2% Time, $n$ = 1 year Let $x$ and $900-x$ be the two parts. Simple interest, SI = $\frac{PnR}{100}$
Question : What is the value of $\frac{56}{7} \times\left(\frac{24}{81} \times \frac{729}{72}\right)+\frac{42}{6}$?
Option 1: 30
Option 2: 32
Option 3: 31
Option 4: 33
Correct Answer: 31
Solution : $\frac{56}{7} \times\left(\frac{24}{81} \times \frac{729}{72}\right)+\frac{42}{6}$ $=8×(3)+7$ $=24+7$ $=31$ Hence, the correct answer is 31.
Question : What will the curved surface area of a cylinder with a radius of 10 cm and height of 20 cm? (use $\pi=3.14$)
Option 1: 1345 cm2
Option 2: 1453 cm2
Option 3: 1256 cm2
Option 4: 1234 cm2
Correct Answer: 1256 cm2
Solution : Given: A cylinder with a radius of 10 cm and height of 20 cm. The curved surface area of a cylinder with a radius $r$ and height $h$ $=2\pi rh$ $=2\times 3.14\times 10\times 20=1256$ cm2 Hence, the correct answer is 1256 cm
Question : Directions: Select the number from among the given options that can replace the question mark (?) in the following series. 503, 509, 521, 539, ?
Option 1: 576
Option 2: 545
Option 3: 563
Option 4: 535
Correct Answer: 563
Solution : Given: 503, 509, 521, 539, ?
Add the multiples of 6 to the previous number to obtain the next number of the series – 503 + 6 = 509, 509 + 12 = 521, 521 + 18 = 539, 539 + 24 = 563

Option 1: 21.33%
Option 2: 24.13%
Option 3: 29.17%
Option 4: 32.66%
Correct Answer: 29.17%
Solution : Total Bottles C4 and C5: = 42 + 28 = 70 Total Bottles for all 6 colours: = 46 + 34 + 50 + 42 + 28 + 40 = 240 Now, Percentage = $\frac{70}{240}$ × 100 = 0.291 × 100 = 29.17 Hence, the
