P5 Math Question :
Mr Goh had some badminton rackets.
On Monday, he sold 0.25 of them.
He sold 20 fewer badminton rackets on Tuesday than on Monday.
If he had 160 badminton rackets left, how many badminton rackets did he have at first?
Given Selection : (a) 240 (b) 280 (c) 320 (d) 360
Correct Answer is (d) 360
WHY?

Monday = 1/4 <-- 1U
Tuesday = 1/4 - 20 <-- 1U - 20
Remaining = 160 <-- 2U + 20

2U + 20 = 160
2U = 160 - 20
2U = 140
1U = 70

Total Badminton Rackets = 70 x 4 = 280.
Why is the answer 360?
