Answer 1

Answer:

35 years old

Step-by-step explanation:

Let the Sameer be '$a$ years old' at present.

Then Monshaka is '$a+5$ years old'.

Govinda is '$a+10$ years old.'

Five years ago, Sameer was '$a-5$ years old.'

Monshaka was '$a$ years old.'

Govinda was '$a+5$ years old.'

The ratio of their age was $(a-5):(a+5)$.

According to the passage, the ratio of their age was $5:7$.

Which means $(a-5):(a+5)=5:7$.

Use proportion of ratios, and we have the following :

$5(a+5)=7(a-5)$

$5a+25=7a-35$

$2a=60$

∴ $a=30$

Monshaka is '35 years old' at present.
