Question
Anju spends 16% of her monthly income on rent, 22% of it
on groceries, 14% of it on children's education and 50% of the remaining on other items. If ₹ 22,852 is left with her at the end of the month, then what is her monthly income (in, ₹)?Solution
Solution-Let the monthly income of Anju= 100 Rs
Total Expend on rent ,groceries and education =16+22+14=52
Remaining =100-52=48
Spend of other item =48×60/100
=28.8
And now remain =48-28.8=19.2
ATQ-
19.2=22852
1=22852/19.2=1190.20
100=116020
Monthly income =116020
