A man gave 35% of his money to his elder son and 40% of the remainder to his younger son. If he is left with Rs.23400, find how much money did he have originally?

salary given t0 elder son = 35%

salary given to younger son = 40 %

it is given that he is left with rs 23400 which is 25% of his salary

so let his orignal salary be X

23400 = x - (x * 25/100)

23400 = x - 25x/100

23400 = 100x - 25x /100

23400= 75x /100

x = 23400 * 100 / 75

after cutting u get

7800 * 4

= rs 31200

so his orignal salary was rs 31200

hope i was able 2 solve your query....thumps up....if  it helps...!!

but how can it be 6000 if after spending he was left with 23400
