Question

the age ram is 6 whole 1 by 4% more than the age of Shyam find how much percent is the age of shyam less than that of Ram​

Answer 1

$\huge{\underline{\sf{Solution:-}}}$

★ Given:-

• Salary of Ram = 25% more than Shyam

• Let the salary of Shyam = Rs. 100

Then, salary of Ram = 100 × 25/100 + 100

= 25 + 100 = 125 Rs.

★ To find:-

By what % Shyam's salary is less than Ram's ?

$\huge{\underline{\sf{Explaination:-}}}$

★ Method I:-

Required % = Salary difference/Ram's salary × 100

= 125 - 100/125 × 100

= 25/125 × 100

$\boxed{\sf{= 20\: percent}}$

Hence, the required answer = 20%

★ Method II:-

25% = 25/100 = 1/4

Shyam: 4 parts → Ram(25% more) : 5 parts[25% of '4' = 1]

★ To find:-

• By how much % 4 is less than 5

= 5 - 4/5 × 100 = 1/5 × 100 = 20%

★ Method III:-

By what % less = Given %/(100 + given%) × 100

= 25/(100+25) × 100

$\boxed{\sf{= 20\: percent}}$
