Question
Roshan spends 80% of the money that he receives every month and saves ₹ 2500. How much money does he get monthly?
Let the total money be x.
Then, Amount spend = `square/100`
Amount saved = ₹ `square`
Now, `square/100 + square` = x
`x - square/100 = square`
`square/100 = square`
x = `(square xx 100)/square`
x = `square`
Hence, Roshan get ₹ `square` as monthly Salary.
Solution
Let the total money be x.
Then, Amount spend = `bb(80x)/100`
Amount saved = ₹ 2500
Now, `bb(80x)/100 + bb2500` = x
`x - bb(80x)/100 = bb2500`
`bb(20x)/100 = bb2500`
x = `(bb2500 xx 100)/20`
x = 12,500
Hence, Roshan get ₹ 12,500 as monthly Salary.

A two-digit number and the number with digits interchanged add up to 143. In the given number the digit in unit’s place is 3 more than the digit in the ten’s place. Find the original number.
Let the digit in unit’s place is x
and that in the ten’s place is y
∴ the number = `square` y + x
The number obtained by interchanging the digits is `square` x + y
According to the first condition two digit number + the number obtained by interchanging the digits = 143
∴ 10y + x + `square` = 143
∴ `square` x + `square` y = 143
x + y = `square` ........(I)
From the second condition,
digit in unit’s place = digit in the ten’s place + 3
∴ x = `square` + 3
∴ x − y = 3 ........(II)
Adding equations (I) and (II)
2x = `square`
x = 8
Putting this value of x in equation (I)
x + y = 13
8 + `square` = 13
∴ y = `square`
The original number is 10 y + x
= `square` + 8
