221. If the heights of two cones are in the ratio 1:4 and their diameter are in the ratio 4:5 what is the ratio of their volumes?

a. 1:4 b. 4:25 c. 4:23 d. 1:6

Ans: 4:25

Volume of a cone = (1/3) * Pi * r

^{2}*h
Ratio of volumes = (4 * 4* 1)/ (5 * 5 * 4) = 4: 25

222. A cylinder of height 14 cm has a volume of 1100 cm

^{3}determine the base radius of the cylinder.
a. 10 cm b. 7.5 cm c. 5 cm d. 2.5 cm

Ans: 5 cm

Volume of a cylinder = Pi * r

^{2}* h
1100 = (22/7) * r

^{2}* 14
r=5 cm

223. Find the time in which Rhett can cover a distance of 3 km running at a speed of 12m/minutes.

a. 4.16 hours b. 4.10 hours c. 4 hours d. 4.25 hours

Ans: 4.10 hours

Convert given speed into km/hour

12m/minutes= ( 12 (1/1000))/1/60 = 12*60 / 1000 kmph

Time = distance / speed = 4.10 hours

224. Find the remainder when 83*85*87*88*91 is divided by 41.

a. 32 b. 31 c. 29 d. 34

Ans: 31

Divide individual terms with 41 find out remainder

That is (1 * 3 * 5 * 6 * 9)/41 = 31

225. If the selling price of an article is (2/3)

^{rd}of its cost price, then find the profit/loss percent.
a. 20% profit b. 33% profit c. 33% loss d. 20% loss

Ans: 33% loss

Let’s say cost price is x

Then selling price = (2/3)* x

Profit or loss % =( ( selling price – cost price )/ Cost price ) * 100

= 33% loss ( negative sign indicates loss )
