Given :-
In a particular month Mr. Rao spent 5400, which was 20% of his monthly salary on food.
To find :-
(a)His monthly salary
(b) If he saved 15% of his monthly salary, then his monthly savings.
Solution :-
Let the monthly salary of Mr. Rao be Rs. X
Money spent on his food = 20% of his salary
= 20% of X
= 20% × X
= (20/100)×X
= (1/5)×X
= Rs. X/5
Money spent on his food = Rs. X/5
According to the given problem
Money spent on his food = Rs. 5400
=> X/5 = 5400
=> X = 5400×5
=> X = Rs. 27,000
a) His monthly salary = Rs. 27,000
His monthly savings
= 15% of his monthly salary
=> 15% of 27000
=> 15% × 27000
=> (15/100)×27000
=> (15×27000)/100
=> 15×270
=> Rs. 4050
His monthly savings = Rs. 4050
Answer :-
a) Monthly salary of Mr. Rao
= Rs. 27,000
b) Monthly savings of Mr. Rao
= Rs. 4,050
