Question

Last year, Mr. X saved 10% of his annual earnings. This year he earned more than
last year and he saved 12% of his annual earnings. If the amount saved this year is
126% of the savings of previous year, how much more did he earn this year?​

Answer 1

Step-by-step explanation:

Suppose total earnings = Rs. 10000

10% saving = 10000 x (10/100) = Rs. 1000

This year 5% more income than prev year = Rs. 10500

12% saving = 10500 x (12/100) = Rs. 1260

Percentage of amount saved = (1260/1000) x 100

= 126%

Answer 2

Answer:

Step-by-step explanation:

earning of last year = x
savings = .1x
earning of this year = y

savings = .12y

so,
.12y = 126% of .01

.12y = 1.26* 0.1

12y = 126* 0.1

120y=126x

y/x=126/120=21/20

(y-x)/x = (21-20)/20 = 1/20*100%=5%
