?^3 = 343 × 64
? = 28
2. 5
? = (250×3458 + 162×1450)/100
= (864500 + 234900)/100
= 10994
3. 1
? = (145×69×252×348)/ 6480
= 135401
4. 1
? = 144/13 + 31/39 + 27/13 + 41/39
= (432 + 31+ 81+ 41)/39 = 15
5. 4
? = (144×158×164)/16×9×8 = 3239
Profit = Income - Expenditure
%Profit = (Income - Expenditure) x 100 / Expenditure
