#Average

Ans (d) 35
First take out the average of the combine amount i.e total amount (118) ÷ total no. of children (50) = 2.36
Then use the alligation method
Ratio b:g = 3:7
3x+7x = 50
x=5 hence no. of girls =7×5 =35

Girls 3 means 3 ×5= 15 only

[@VivekSingh-ei9ms]

​@@shalinishalu9773 you are wrong you took the wrong ratio values girls are 7x and boys are 3x ........ also if you cross check your answer by multiplication of the rupees the sum will be 102 and not 118 so... kindly focus while taking the values
