Question

. A man spends 30% of his income in board and lodging, 25% of the remainder in other personal
necessities and 20% of the rest in Charity. If his income is Rs. 25000, find the amount left by

Answer 1

Let his income be x

Then,

75% of 80% of 50% of x = 4200

3/4 * 4/5 * 1/2 * x = 4200

12/40 * x = 4200

x = 4200*40/12

x = 350 *40

x = 14000

Answer 2

Concept introduction:

Spending money is cash that you own or get for purely recreational purposes, especially when travelling.

Given:

• Here it is given that the man spends $30$ % of his income in board
• $25$ % of the remainder in other personal necessities
• $20$%  of the rest in Charity.
• His income is Rs. $25000$.

To find:

We have to find the amount which is left by the man.

Solution:

According to the question, he spent total amount of Rs.

$[(25000*30/100)+(25000*25/100)+(25000*20/100)]\\=7500+6250+5000\\=18750$

His income is about $Rs. 25000$  So, the amount left by is ->

$(25000-18750)\\=6250$

Final answer:

Hence, the final answer of the question is => $6250$.
