Question

After spending 4/9 of her money,Nindhi had ₹45 Left .how much did she spend?

Answer 1

Let the total money was Rs x ,

Given in question that after spending 4 / 9 of her money which was Rs x , she had Rs 45 left,

According to the question,

Rs x - ( 4 / 9 of Rs x ) = Rs 45

x - ( 4 / 9 × x ) = 45

x - ( 4x  / 9 ) = 45

( 9x - 4x ) / 9 = 45

5x = 45 × 9

x = ( 45 × 9 ) / 5

x = ( 9 × 9 )

x = 81

Total money = money spend + money left

81 = money spend + 45

81 - 45 = money spend

Rs 36 = money spend

Answer 2

Given...

After spending 4/9 of her money,Nindhi had ₹45 Left

Let total money be x and expenditure be (4/9)x

then

x - 4x/9 = 45

9x - 4x / 9 = 45

5x = 405

x = 405/5

x = 81

So total money = 81

expenditure = 4/9 of money = 81×4/9= 36
