यदि `37^(**)14=17`,
`69^(**)33=34`
`91^(**)125=72`
हो, तो `28^(**)56=? `

Options

A. 26
B. 42
C. 34
D. 28

Answer

D

Explanation

`37^(**)14=17`
`rArr(37+14)/(3)=17rArr(51)/(3)=17`
`69^(**)33=34rArr(69+33)/(3)=34`
`rArr(102)/(3)=34`
`91^(**)125=72rArr(91+125)/(3)=72`
`rArr(216)/(3)=72`
अतः
`28^(**)56`
`rArr(28+56)/(3)rArr(84)/(3)=28`
