Given : 100 student in a classroom like i-phone or samsung mobile or both mobiles. out of them,40 like both mobiles. if the ratio of number of student who like i-phone and samsung is 3:2
To Find : the number of student who like i-phone only.
Solation:
Like I phone = 3x
Like Samsung = 2x
Like Both = 40
100 = Samsung + Iphone - Both
=> 100 = 2x + 3x - 40
=> 5x = 140
=> x = 28
Like I phone = 3x = 3 * 28 = 84
Like Samsung = 2x = 2 * 28 = 56
like i-phone only. = I phone - both
