Question

billy gave his sister 40% of his pocket money and was left with 150$. How much money in his pocket ($)?

Answer 1

Answer:

$250

Step-by-step explanation:

1) 100% - 40% = 60% (40% deducted because Billy gave 40% of total amt to his sis)

2) 60% = $150 (he was remaining with 60% of total amount and that amt was $150)

3) If 60% is $150,

then 100% is $?

= 100 × 150 = 15000

15000/60 = $250 (cross multiplication)

Answer 2

Step-by-step explanation:

% of money Billy gave his sister = 40%

Amount of money left = 150$

Money in Billy's pocket = ( 40% - 100% )

= 60% = 150$

so,

let the total amount of money be x

60% of x = 150

60/100 × x = 150

x = 150 × 100 / 60

x = 250$

Total amount of money Billy had was 250$

hope this helps you.
