From his monthly salary a man spends 10% of his salary for house rent, 20% on food, 25% for all other expenses and saves Rs 2520 per month. His monthly salary is? | [
"Rs 5880",
"Rs 5600",
"Rs 4200",
"Rs 4000"

His spending are on house rent 10%, on food 20% and for other expenses 25%.
Total expenditure = 10 % + 20% + 25% = 55%
His savings are => Income – Expenses
=> 100% - 55% => 45% = Rs 2520
Hi salary is 1005 => 2520 45

=> [12/ (x-y)] - [12 / (x+y)] = 6.
=> y = ( x2 - y2 ) / 4. ..................(i)
When Rahul doubles his rowing rate, then we have :-
