Answer:
No. of balloons left with Tarun is MORE than 10
but LESS than 15.
10 < No. of balloons left with Tarun <15
Explanation:
this is problem of inequality . first we will try to write the existing condition in inequality form then apply other situation as given in the problem.
___________________________________________________
let the no . of balloons with Tarun be x
Given he has is MORE than 15 balloons
thus, in equality it can be represented as
x > 15
he has LESS than 20 balloons
x < 20
combining both we have
15 < x < 20
now he gives 5 of them to sia
so we have to subtract 5 from inequality
he has left with him x-5 , let x-5 be y
thus,
subtracting 5 from each part of inequality
15 -5 < x-5 < 20 -5
10 < x-5 < 15
10 < y <15
Thus, No. of balloons left with Tarun is MORE than 10
but LESS than 15.
