A) 2400
B) 2520 ✓
C) 2600
D) 2750
Explanation:-
Answer: B
Discuss it below :
Let the required wages be Rs. x.
More men, More wages (Direct Proportion)
Less days, Less wages (Direct Proportion)
Men 6: 9 : : 2100:x
Days 15:12
Therefore (6 x 15 x x) = (9 x 12 x 2100)
x = (9 x 12 x 2100)/(6 x 15) = 2520
Hence the required wages are Rs. 2520.
