There are thrice as many yellow shirts as green shirts in a sale. If there are 144 yellow and green shirts altogether,
- how many yellow shirts are there?
- how many more yellow shirts than green shirts?
(a)
Number of green shirts = 1 u
Number of yellow shirts
= 3 x 1 u
= 3 u
Total number of shirts
= 3 u + 1 u
= 4 u
4 u = 144
1 u = 144 ÷ 4 = 36
Number of yellow shirts
= 3 u
= 3 x 36
= 108
(b)
Number of more yellow shirts than green shirts
= 3 u - 1 u
= 2 u
= 2 x 36
= 72
Answer(s): (a) 108; (b) 72
