Answer 1

AnswEr :-

• Original salary of the man is 16,000.

Given :-

• On increasing the salary of a man by 25%, it becomes 20,00.

To Find :-

• Original salary of the man.

SoluTion :-

→ Let original salary of man be x

→ New increased salary = 25% of x + x

» (25/100 × x) + x

→ (1/4 × x) + x

→ x/4 + x

→ 5x/4

★ According to question :-

» 5x/4 = 20,000

→ 5x = 20,000 × 4

→ 5x = 80,000

→ x = 80,000/5

→ x = 16,000

Hence, the original salary of the man is 16,000.
