OPtion
1) 12 days
2) 12.5 days
3) 13.2 days
4) 14 days
5) 15.27 days
6) 18 days
7) 18.27 days
8) 19.25 days
9) 14.56 days
10) None of the above
Solution
Let the total money be Rs.x
Suraj’s 1 day salary = Rs. x/24
Devesh’s 1 day salary = Rs. x/42
(Suraj + Devesh)’s 1 day salary = Rs(x/24+x/42)
= (4x+7x)/168 =11x/168
x = 168/11 = 15.27
Money is adequate to pay the salary of both for 15.27 days.
