Question : If A is 40% less than B and C is 40% of the sum of A and B, then by what percentage is B greater than C?
Option 1: 60
Option 2: $56 \frac{1}{4}$
Option 3: $40 \frac{1}{8}$
Option 4: 36
Correct Answer: $56 \frac{1}{4}$
Solution : Let B = 100 So, A = 60 $\therefore$ C = 40% of (60 + 100) = 64 So, B is greater than C by $= (100 - 64) × \frac{100}{64}$ $= (\frac{225}{4})\%$ $=56\frac{1}{4}\%$ Hence, the correct answer is $56\frac{1}{4}\%$.
Question : A and B can do a certain work in 6 hours, and A, B, and C together take 4 hours to do the same. How long will it take for C alone to accomplish the task?
Option 1: 12 hours
Option 2: 4 hours
Option 3: 2 hours
Option 4: 6 hours
Correct Answer: 12 hours
Solution : 1 hour task of (A + B) = $\frac{1}{6}$ 1 hour task of (A + B + C) = $\frac{1}{4}$ The task done by C alone in a day = $\frac{1}{4}-\frac{1}{6}$ = $\frac{6-4}{24}$ = $\frac{2}{24}$ = $\frac{1}{12}$ So C alone can complete the whole
