Question 9

What is the area (in sq cm) of a rectangle of perimeter 48 cm and breadth 10 cm?

Accepted Answer

Perimeter = 2(L + B) = 48. So, L + 10 = 24, which gives L = 14 cm. Area = L × B = 14 × 10 = 140 sq cm.

80 litre mixture of milk and water contains 10% milk. How much milk (in litres) must be added to make water percentage in the mixture as 80%?

Accepted Answer

Initial water is 90% of 80L = 72L. Let x be the added milk. Water remains constant, so 80% of (80 + x) = 72. Solving gives 80 + x = 90, so x = 10L.

Question 11

50% of a = b, then b% of 40 is the same as _________ of a.
