Question

Hi

Need some help for this P6 math question. Thank you.

Answer

(a)
Day 1 :
female participants —— 10 units
male participants ——- (10 units – 60)

Day 2 :
female participants —— 10 units x (100% – 20%) = 8 units
male participants ——- (10 units – 60) x (100% + 30%) = 13 units – 78

8 units + 13 units – 78 ——- 573
1 units ——- (573 + 78)/(8 + 13) = 31
10 units + 10 units – 60 = 20 units – 60 ——- 20 x 31 – 60 = 560

(b)
560 + 573 = 1133
1133 x 55 = 62315
62315 x (100% – 10%) = 56083.50

Ans : (a) 560 participants; (b) $56083.50.

This is a Matrix question.

   Male Female  Total   
Day 1  100u 100u + 60 200u + 60
Day 2 130u 80u + 48 210u + 48
Total       

 

210u + 48 = 573

210u = 573 – 48 = 525

1u = 525 ÷ 210 = 2.5

a)

200u = 200 × 2.5 = 500

500 + 60 = 560

b)

573 + 560 = 1133

1133 × 55 × 90/100 = $56083.50
