Question

Rakesh's height is 0.6 m. If his mother's height is thrice of his height, then what is his mother's height(in m)?

• A. 0.6
• B. 1.2
• C. 1.8
• D. 2.4

Answer 1

The correct option is C 1.8

$\text{Rakesh's height}=0.6\text{m}$
$\text{Rakesh's mother height}=3\times 0.6\text{m}$
Multiplying ignoring the decimal we get
= 6 x 3 = 18
As the decimal place in the 0.6 is after one place form the right so we have to place decimal point after one place in 18 as well, hence we get 1.8
Therefore, Rakesh's mother height is 1.8 m
