Answer 1

Answer:  

if he spent 1/4 th of his savings he has 3/4th of his money and 2/5 th of remaining is spent so, he has 3/4 - 2/5 =7/20 th of original money he has

let total amount be x rupees

then 3/4 x - 180 = 7/20 x

if u solve u will get, x=450 rupees:

Answer 2

Step-by-step explanation:

let x be his savings,

spent on trousers = x/4

remaining = x -x/4 = 3x/4

spent on book = (3x/4) (2/5) = 3x/10

fraction of savings left with him = 3x/4 - 3x/10 = 9x/20

or 9/20

3x/10 = 180

x = 180 × 10/3

x = Rs 600

so, he had RS 600 originally.
