Question

a man lost 20% of his wealth after spending 25% of remaining wealth, he has left with RS 480 find the initial wealth ​

Answer 1

let the initial wealth be x

after losing 20% , he will have 80%

80% of x = (80/100 ).x

= 4x/5

remaining = 4x/5

now , he lost 25 % from remaining wealth., he will have 75%

75% of 4x/5

= (75/100)×(4x/5)

= (3/4).(4x/5)

= 3x/5

now , 3x/5 = 480

=> x = 480×5/3

=> x = 800 .
