Question

the wage of worker if increased by 10% becomes ₹154. by what percent is the wage to be increased to make it ₹175

Answer 1

the wage of workers if increased by 10% becomes 154

so, 10% of x + x = 154
10%x + 100%x = 154
110% x = 154
(110x/100) = 154
110x = 15400
x = 15400/110
x = 140

before increment the wage of workers is 140

what percentage is the wage to be increased to make it 175

140 + 140y% = 175
140 + (140y/100)= 175
(14000 + 140y)/100=175
14000 + 140y = 17500
140y = 17500 - 14000
140y = 3500
y = 3500/140
y = 25

so 25% of increment in 140 becomes 175
