If a person having 1000 Rs and he want to distribute this to his five children in the manner that each son having 20 rs more than the younger one, what will be the share of youngest child?
160
150
155
120
Explanation:
Assume first child (the youngest) get = x Rs.
According to the question ;
each son having 20 rs more than the younger one
2nd child will get = x + 20 Rs
3rd child will get = x + 20 + 20 = x + 40 Rs
4th child will get = x + 20 + 20 + 20 = x + 60 Rs
5th child will get = x + 20 + 20 + 20 + 20 = x + 80 Rs
Total amount they got = 1000 Rs
=> x + (x+20) + (x+40) + (x+60) + (x+80) = 1000
=> 5x + 200 = 1000
=> 5x = 800
=> x = 160 Rs.
So, the youngest child will get 160 Rs.
