Question

a man spent 72 percentage of his salary and remaining were his savings. if he saved 7200rupees per month,find his monthly income.
please help me​

Answer 1

Answer:

Let monthly income = X

spent amount= X of 72%

= 18X/25

saved amount=7200

monthly income = saved amount + spent amount

X = 7200 + 18X/25

X = 180000/7

X = 25714

The monthly income is Rs 25714

Answer 2

Given,

a man spends 72% of his salary

his savings per month= ₹7200

To find:

the man's monthly income

Let:

the man's monthly income= x

his savings per month=y

Solution:

since,

total spendings=72%of salary

so,

total savings=(100-72) =28%

savings = y

=> 28%of x =y

=> 28%of x = ₹7200 (given)

=> x =7200×100/28

=> x =25714.286 (approx)

hence,

x's monthly income=₹25714.286
