Question

varun spent 1/4,of his savings on a pair of trousers and 2/5of the remaining savings on a book. what fraction of his savings is left with him. and if the book coats Rs 180 how much money did he have originally​

Answer 1

Answer:

600

Step-by-step explanation:

SOLUTION

Let amount varun have be x

then

expenses on pair of trousers= 1/4 of x= x/4

Remaining amount=X -(x/4)

=(4x-x)/4

=3x/4

and expenses on book= 2/5 of 3x/4

=(2×3x)/(5×4)

=6x/20

= 3x/10

amount left with him= 3x/4-3x/10

=(30x-12x)/40

=28x/40

=7x/10

but by question,

or, 3x/10 =180

or, 3x=180×10

or, 3x= 1800

... x=600
