Shiva gave 40% of his monthly salary to his mother from the remaining he used 7% for electronic gadgets and 23% hekept aside for his monthly expenses. The remaining amount he transferred to his friend's account. The sum of theamount he gave to his mother and he transferred to his friend account was 41000. What was Shiva's monthly salary?
Given:
Salary given to his mother = 40% = 2/5
From the remaining, he used for electronic gadgets and monthly expenses = (7 + 23)% = 30% = 3/10
Sum of the amount he gave to his mother and transferred to his friend account = Rs 41000
Calculation:
Let the sum of amount be 50 unit. (where 50 = product of denominator of given fraction 5 × 10)
Salary given to his mother = (2/5) × 50 = 20 unit.
Remaining salary after gave to his mother = 50 – 20 = 30 unit.
Electronics gadgets and monthly expenses from the remaining = (3/10) × 30 = 9 unit.
Remaining amount which transferred to his friend's account = 30 – 9 = 21 unit
Sum of amount he gave to his mother and his friend's account = 41000
⇒ (20 + 21) unit = 41000
⇒ 41 unit = 41000
⇒ 1 unit = 41000/41
⇒ 1 unit = 1000
⇒ (1 × 50) unit = 1000 × 50
⇒ 50 unit = 50000
∴ The monthly salary of Shiva is Rs. 50000 .
