4/5 of classmates running behind Yazid
so,
4/5 classmates = 7/9 total number
classmates = 35/36 total number
total number --> 36

Hi whywhy,

It is 185 degree. Maybe he calculated wrongly

PTR = 180 - 65 = 115
RTS = 60
PTS = 360 - PTR - RTS
= 360 - 115 - 60
= 185

Cheers :celebrate:

Please help me to solve this question. Thanks.


A fruit seller sells a kiwi at $0.80 and an apple for $0.30.
He sells at $3.00 per pack for every 4 kiwis bundle with a free apple.
After selling the apples and kiwis, the number of apples is 3/10 the number of kiwis he sells.
If he collects a total amount of $38.50, how many kiwis more than apples does he sell ?
