Question: 1

The radii of the front wheel and the rear wheel of a bike are 14 cm and 21 cm respectively. Rahul puts a red mark on the point on contact of each of the wheels, with the ground when the bike is stationary. Once the bike starts moving, then after what distance will the two red marks touch the ground again simultaneously?

(A) 84 cm

(B) 264 cm

(C) 274 cm

(D) 294 cm

Ans: B

Circumference of the front wheel = $$(2 × {22}/{7} × 14)$$ cm = 88 cm.

Circumference of the rear wheel = $$(2 × {22}/{7} × 21)$$ cm = 132 cm.

Required distance = L.C.M. of 88 cm and 132 cm = 264 cm.

Question: 2

The two parallel sides of a trapezium are 1.5 m and 2.5 m respectively. If the perpendicular distance between them is 6.5 metres, the area of the trapezium is

(A) 10 m2

(B) 13 m2

(C) 15 m2

(D) 18 m2

Ans: B

Area of trapezium = $$[{1}/{2} × (1.5 + 2.5) × 6.5]$$m2 = 13 m2.

Question: 3

The area of the rectangle circumscribed by a circle is 32 cm2 and the length of one side of the rectangle is 8 cm. The length of the diameter of the circle is

(A) 4$$√5$$ cm

(B) 5$$√2$$ cm

(C) 12 cm

(D) 16 cm

Ans; A

Area of the rectangle = 32 cm2.

One side = 8 cm.

Other side = $$({32}/{8})$$ cm = 4 cm

∴ Diameter of the circle

= Diagonal of the rectangle = $$√ 8^2 + 4^2$$

= $$√80$$ cm = $$4√5$$ cm.

Question: 4

The diameter of the driving wheel of a bus is 140 cm. How many revolutions per minute must the wheel make in order to keep a speed of 66 kmph?

(A) 150

(B) 250

(C) 350

(D) 450

Ans: B

Distance to be covered in 1 min = $$({66 × 1000} / {60})$$m = 1100 m.

Circumference of the wheel = $$(2 × {22}/{7} × 0.70)$$m = 4.4 m.

∴ Number of revolutions per min. $$({1100} / {4.4})$$ = 250.

Question: 5

What is the maximum number of identical square titles required to tile a floor of length 6 m 24 cm and width 4 m 80 cm?

(A) 110

(B) 122

(C) 130

(D) 140

Ans: C

Length of largest tile = H.C.F. of 624 cm and 480 cm = 48 cm.

Area of each tile = (48 × 48) cm2.

∴ Required number of tiles = $$({624 × 480}/{48 × 48})$$= 130.
