Question

Sekhar gives a quarter of his sweets to Renu and then gives 5 sweets to Raji. He has

7 sweets left. How many did he have to start with?​

Answer 1

16 sweets

Explanation:

Number of sweet that Sekhar had = x

Sweets given to Renu = (1/4) of x =
`(1)/(4)x`

Sweets given to Raji = 5

Remaining sweets = 7

`x = (1)/(4)x +5 + 7\\\\x -(1)/(4)x = 12\\\\(4*x)/(1*4)x-(1)/(4)x = 12\\\\(4x)/(4)-(1)/(4)x= 12\\\\(3x)/(4)=12\\\\x = 12*(4)/(3)\\\\x=4*4\\\\x=16`
