If a man cycling along the boundary of the park at the speed of 12 km/hr completes one round in 8 minutes, then the area of the park (in sq. m) is: 15360 153600 30720 307200 Perimeter = Distance covered in 8 min. = 12000 × (8/60) = 1600 m. Let length = 3x metres and breadth = 2x metres. Then, 2(3x + 2x) = 1600 or x = 160. So Length = 480 m and Breadth = 320 m So Area = (480 x 320) m2 = 153600 m2 12. 12 buckets of water fill a tank when the capacity of each bucket is 13.5 litres.

Shyam purchased some goods for Rs 1800. He sold one-third of the goods purchased at 20% loss. Find the profit percentage at which the rest of the goods must be sold to realize an overall profit of 20% 20% 40% 30% 80% Suppose that shyam purchased x goods for Rs 1800. Cost price of 1 good = 1800/x He sold one third at a loss of 20%. Hence his selling price of this goods = 0.8×(1800/x)×(x/3)= Rs 480. His total selling price must be 1.2 × 1800 = Rs 2160 Hence selling price of the remaining two-third must be Rs 1680. Cost price of two-third i.e. 2x/3 ×(1800/x)= rs 1200 Profit %=( 1680-1200)/1200 ×100= 40% 16.
