OPtion

1) 3040
2) 3820
3) 3280
4) 4820
5) 5560
6) 4280
7) 5320
8) 3400
9) 5280
10) None of these

Solution

Let last year price=100 and required raw material= x kg, so expenditure=100x
This year, price=(100-24)=76 and requirement=(x+240) kg, so expenditure=76(x+240)
Current year expenditure = (100-18)% or 82% expenditure of previous year
76(x+240) = (82/100)*100x
38(x+240) = 41x
3x = 9120
x = 3040
.'. Current requirement = 3040 + 240 = 3280 Kg.
