The average of 3 numbers is 120. The largest number is 165 while the difference between the other two is 15. Find the smallest number:
Explanation:
Sum of the three numbers = 3 × 120 = 360
Let the other two numbers be ‘x’ and ‘x – 15’.
⇒ 165 + x + x – 15 = 360
⇒ 2x = 210
⇒ x = 155
∴ The smallest number = x – 15 = 140
Hence, option (d).
