Question

The cost and weight of 4 metal balls are given as follows:

All the balls have the same relation between the cost and the weight except one. Find the ball which follows a different relation than others?

• A. Ball 1
• B. Ball 2
• C. Ball 3
• D. Ball 4

Answer 1

The correct option is D Ball 4

Here, all the balls except Ball 4 follows the same relation as:

Weight $\times$ 12 + 20 = Cost

Ball $1$: $15\times 12+20=200$
Ball $2$ : $17\times 12+20=234$
Ball $3$: $21\times 12+20=272$
Ball $4$ : $33\times 12+20=416$

Clearly, Ball 4 follows a different relation here.
