Question

A man's basic pay for a 40 hour week is Rs.20. Overtime is paid for at 25% above the basic rate. In a certain week he worked overtime and his total wage was Rs.25. He therefore worked for a total of :

a) 45 hours
b) 47 hours
c) 57 hours
d) 46 hours

Answer 1

Basic rate per hour = Rs.(20/40)= Rs.1/2

Overtime per hour = 125% of Rs.1/2=125/100×1/2=Rs.5/8

Suppose he worked x hours overtime.

Then,

20+5x/8=25

or, 5x/8=5

x=(5×8)/5=8 hours

So he worked in all for (40+8) hours = 48 hours ANS

this will be the correct ans i am 100% sure .there is a printing error in the papper
