Given : prize money of Rs 900 is to be distributed among 11 children each girl is to receive Rs 100 and each boy is to receive Rs 50
To find : number of boys & girls
Solution:
Prize money = Rs 900
Total Children = 11
Let say total Girls = G
=> Total Boys = 11 - G
Each girl to receive Rs 100
Hence amount received by Girls = 100G Rs
Each Boy to receive Rs 50
Hence amount received by boys = 50(11 - G) = 550 - 50G Rs
Total Amount = 100G + 550 - 50G
= 50G + 550
50G + 550 = 900
=> 5G + 55 = 90
=> 5G = 35
=> G = 7
Number of Girls = 7
Number of Boys = 11 - 7 = 4
