Question : A can do $\frac{1}{3}$rd of a piece of work in 32 days, B can do $37 \frac{1}{2}$% of the same work in 24 days, while C can do 60% of the same work in 48 days. B and C together started and worked for x days. After x days, B left and A joined C and together, completed the remaining work in (x + 8) days. If the ratio of the work done by (B + C) together to the work done by (A + C) together is 9 : 11, then what fraction of the same work can be completed by C alone in 3.5x days?
Option 1: $\frac{18}{25}$
Option 2: $\frac{4}{5}$
Option 3: $\frac{7}{10}$
Option 4: $\frac{3}{4}$
Correct Answer: $\frac{7}{10}$
Solution : Given: A can do $\frac{1}{3}$ of a task in 32 days. Total work done = Number of days × Efficiency So, A can complete the task in 32 × 3 = 96 days B can do $37 \frac{1}{2}$% of the same task in 24 days,

His answer was $\frac{6}{7}$. What is the difference between the correct answer and his answer?
Option 1: $\frac{9}{14}$
Option 2: $\frac{5}{14}$
Option 3: $\frac{11}{49}$
Option 4: $\frac{6}{49}$
Correct Answer: $\frac{6}{49}$
Solution : Given: $\frac{\left(2 \frac{1}{3}+2 \frac{1}{2}-\frac{1}{6}\right) \div 2 \frac{1}{3} \times 5 \frac{2}{3} \div 1 \frac{2}{3} \text { of } 4 \frac{1}{4}}{3 \frac{1}{5} \div 4 \frac{1}{2} \text { of } 5 \frac{1}{3}+5 \frac{1}{3} \times \frac{3}{4} \div 2 \frac{2}{3}}$ = $\frac{(\frac{7}{3}+\frac{5}{2}-\frac{1}{6}) \div \frac{7}{3} \times \frac{17}{3} \div \frac{5}{3} \text {
Question : Two successive discounts of 30% and 20% are equivalent to a single discount of:
Option 1: 44%
Option 2: 52%
Option 3: 45%
Option 4: 50%
Correct Answer: 44%
