Question

A labour work 60 hour per week and earn rs 2400 as wages. if his per hour wages increased by 40% and duration of work is reduced by 50/3% find the percentage change in his income

Answer 1

answer

50/3%

step by step derivation

60h=2400

1h=40

wages increased by 40%

therefore, 40*40%

=16

which is now

1h=40+16=56

and duration of time reduced by 50/3%

that is, 60h *50/3%

=10

therefore duration of time is,60-10=50

now new overall wage is

rs50*56h=2800

increament is 2800-2400=400

%age change 400/2400*100

which is 50/3%

Answer 2

Answer:

he earned per hour - 2400/60 =40

wages increased by 40% = 2/5

= 40×2/5 =16

total = 40+16 =56

Step-by-step explanation:

deduction of work 50/3% from 60 hours

= 50/3×100= 1/6

1/6×60= 10

remaining = 60-10 = 50 hours

change in his income = 50×58 = 2800

2800-2400 =400

percentage change in his income = 400/2400 ×100

=50/3
