my dad wanna know how to solve the PSLE question no.2
aka*
1) 156 - 72 = 84
3 units --> 84
1 unit --> 28
28 + 44 = 72
2) 1/2 = 7/14
7/14 - 6/14 = 1/14
So 1 unit --> 112 chairs
14 units --> 14 x 112 = 1568 chairs
3) Volume of water = 40 x 60 x 50 = 120 000cm3
Height = volume/Area
Total area = (50 x 40) + (70 x 40)
= 4800cm2
So Height = 120 000cm3/4800cm2 = 25cm
thnks
