Explanation:

Correct Option is 1: 3100

Let the Sunil's salary be 100x
Son's share = 15% of 100x = 15x
Daughter's share = 10% of 100x = 10x
Wife share's = 20% of 100x = 20x
sunil's left money after distributes = 100x - (15x + 10x + 20x) = 55x
Saving by son from his amount = 15x - 60% of 15x = 6x
Saving by daughter from his amount = 10x - 60% of 10x = 4x
Saving by wife from his amount = 20x - 30% of 20x = 14x
Difference between amount left with sunil and three of them = Rs. 961
⇒ 55x - (6x + 4x + 14x) = 961
⇒x=31
= 100x = 3100
The monthly income of sunil is Rs. 3100
