How much
has Alin​

Answer 1

Step-by-step explanation:

qns 1 : sol:--

let the number be x

then x+10=100

x =100-10

x=90

qns 2: sol:--

let the number of girls be x

so, the number of boys is 2x

and the number of boys is 31

then 2x= 31

x =31/2 ( according to me question is wrong bcz

number of girls cannot be in fraction)

qns 3:sol:--

Ahalia has ₹150

then Alin has = 2×150+8

300+8

308
