Sum of two numbers is $98$ and one is $\dfrac{2}{5}$ of the other. The numbers are—

a $70$ and $28$
b $60$ and $38$
c $50$ and $48$
d $80$ and $18$

ব্যাখ্যা

Let the larger number be $x$ ; then $x+\tfrac{2}{5}x=98$ gives $\tfrac{7}{5}x=98$ , so $x=70$ and the other is $\tfrac{2}{5}\times70=28$ . These satisfy both the sum and the ratio condition.
