Question

The ratio of income to savings of a family is 11:2 find the expenditure if the savings is rs 1520

Answer 1

ratio of income and savings =11:2
let income = 11x
savings =2x
given savings =1520
2x=1520
x=1520/2
x=760
income =11x=11*760=8360
expenditure=income - savings
=8360-760
=7600

Answer 2

• given ratio = 11:2
• so, let the income and savings be
• = 11xand 2x respectively
• income=11x
• savings =1520
• so, savings = 2x =1520= 1520÷2
• = 760
• so,x= 760
• now , income = ( 11×760)
• =8360
• Then expenditure= 8360-1520
• = 6840
