A. 48 days
B. 36 days
C. 45 days
D. 50 days
Answer: Option A
Solution(By Examveda Team)
Work done by 2 men = 3 women = 4 boys 1 man = 2 boys 1 woman = $$\frac{4}{3}$$ boys Thus, Boys × days = 4 × 52 boys × days Again, 1 man + 1 women + 1 boys, $$ = 2 + \frac{4}{3} + 1$$ $$ = \frac{{13}}{3}$$ boys Using work equivalent method, boys × day = BOYS × DAYS $$4 \times 52 = \frac{{13}}{3} \times {\text{x}}\,{\text{(let)}}$$ x = 48 daysThis Question Belongs to Arithmetic Ability >> Time And Work
