Question

Rohan saves 30 per
day. If he saves on all
days in February 2016
how much money will
he save in all?
​

Answer 1

Answer:

Correct option is

A

(21x+3y)

Amount of money spend in 1 day = x

So, amount of money spend in 7 days = (7x)

⇒ Amount of money spend in 1 week = (7x)

Amount of money saved in 1 week = y

∴ Income in 1 week = (7x + y)

So, income in 3 weeks = [3 x (7x + y)]

= (21x + 3y)
