Question

Two numbers are in the ratio 3 : 7 if their sum is 50, then the smallest number is

Answer 1

Answer:

let the ratio be x

3x+7x=50

10x=50

x=50/10

=5

then, 3x=3×5=15

7x=7×5=35

Answer 2

• As per the data given in the question, we have to determine the required number.

      Let the required number are $3x$ and $5x$ respectively.

      According to the condition,

      Two numbers are in the ratio $3:7$ , we will write as,

       $\Rightarrow 3x+7x=50\\\Rightarrow 10x=50\\\Rightarrow x=5.$

       So, the Number will be,

       $\Rightarrow 3x=3\times5=15\\\Rightarrow 7x=7\times5=35.$

     Hence, the smallest number will be $15.$
