Answer 2

Answer:

Given:

• Manan multiplied his age (in Years) by 214. the answer WAS a number between 2200 and 2500.

Find:

• Which one of the following could be manan's age.

Calculations:

• Let us assume x as age of manan.

$\longrightarrow\sf{x \times 214}$

$\longrightarrow\sf{11 \times 214}$

$\longrightarrow{\sf{\underline{\boxed{\red{\sf{2354 }}}}}}$

Therefore, 2354 is the age of manan.

VERIFICATION:

$\longrightarrow\sf{2354 ÷ 214}$

$\longrightarrow{\sf{\underline{\boxed{\red{\sf{11}}}}}}$
