If three numbers are in the ratio 2:3:5 and the twice their sum is 100. Find the square of the largest of the three numbers.
Given that three numbers are in the ratio 2:3:5 and the twice their sum is 100
Lets assume three numbers are a,b and c
therefore, $$ 2(a+b+c)=100 $$
=>$$ 2x+3x+5x=50 $$ ( Given that three numbers are in ratio 2:3:5)
Therefore, largest number would be 25 and it's square would be 625.
