Answer of the puzzle Question asked in UPSC exam is : 35 (or 2)
How : Couple went for picnic that means TWO people went picnic (2 people)
They have 5 sons that means more 5 people (5 people)
Each son has 7 sisters but these sisters will be common for all brothers so there are actually only 7 sisters (7 people)
Each sister has 3 babies that mean there would be total 21 babies (21 people)
So total 35 people (2 + 5 + 7 + 21)
