Hi ,
Elder son share = 35%
Remainder = ( 100 - 35 ) = 65 %
Younger son share = 40 % of 65
= ( 40 × 65 ) / 100
= 26 %
The percentage left with the man = 100 - 35 - 26
= 100 - 61
= 39%
According to the problem given ,
39% of total amount = Rs 11700
Total amount = ( 11700) / 39%
= ( 11700 × 100 ) / 39
= Rs 30000
The man had Rs 30000.
I hope this helps you,
:)
