A customer paid you $600 for construction work, out of which, 3/5 of the total amount was spent on the purchase of materials and 1/5 of the remaining was spent on travelling. How much is left after all the deductions ?

A. $120

B. $190

C. $192

D. $240

Answer : C.


Explanation:

    Total amount paid by the customer for the construction work = $600
    Amount spent on the purchase of materials = 3/5 of the total amount = 3/5 * 600 = $360
    Remaining amount = $ (600 - 360) = $240
    Amount spent on travelling = 1/5 of the remaining amount = 1/5 * 240 = $48
    Total amount spent = $ (360 + 48) = $408
    Amount left after both the deductions = $ (600 - 408) = $192
