B. Rs. 600
C. Rs. 900
D. Rs. 750
Answer: Option B
Solution (By Examveda Team)
Ratio of their daily wages = 5 : 6 : 4 Total wage = Rs. 1800 6 × 5x + 4 × 6x + 4 × 9x = 1800 [As A, B, C works for 6, 4, 9 days respectively] Or, 90x = 1800 Or, x = $$\frac{{1800}}{{90}}$$ Total amount of A = $$\frac{{1800 \times 30}}{{90}}$$ = Rs. 600This Question Belongs to Arithmetic Ability >> Time And Work
