Answer 1

Let the required numbers be 2x & 3x.

Then,

$\bf \implies2x + 3x = 100 \\ \bf \implies \: \: \: \: \: \: \: \: \: \: \: 5x = 100 \\ \\ \bf \implies \: \: \: \: \: \: \: \: \: \: \: \: \: x = \frac{100}{5} \\ \bf \implies \: \: \: \: \: \: \: \: \: \: \: \: \: x = \purple{ 20}$

Hence,

$\sf {1}^{st} \: \: Number=> 2(20) = \blue{40} \\ \\ \sf {2}^{nd} \:Number => 3(20) = \blue{60}$

• Thus, Option (c) is correct answer.
