Mr mehra spends 30% of his income in food 10% on charity 25% and is left with 15750 what is his salary? find his savings

Mr mehra's salary is 26250

Step-by-step explanation:

suppose,

Mr mehra's salary is x

so,

He spends in food = 30% of x

= (30/100). x [x%=x/100]

= 30x/100

=3x/10

He spends in charity = 10% of x

=10x/100

=x/10

Money left = 15750

so,

x = 3x/10 + x/10 + 15750

⇒x - 3x/10 - x/10 = 15750

⇒ (10x-3x-x) / 10 = 15750

⇒6x/10 = 15750

⇒6x=157500

⇒x = 157500/6

⇒x = 26250

∴Mr mehra's salary is 26250
