A) 1558

B) 1458

C) 1585

D) 1485

**D*** etailed solution* : {

*The above question had appeared in the CGL Mains 2020*}

Let the greatest number = x

Let the smallest number = y

x = 7y + 50

x – 7y = 50

x-y = 1280

By solving the above equations, we get

-6y = -1230

y = 205

x = 7×205+50

x = 1485

**ANSWER : D) 1485**
