Q 1 - What number of blocks will be expected to develop a divider 4 m long, 3 m high and 13 cm expansive , if every block measures 20 cm *12cm*6.5 cm?
Answer : B
Explanation
Volume of wall = (400*300*13) cm3 Volume of each bricks = (20*12*6.5) cm3 No. of bricks = (400*300*13 /20*12*13)*2 = 1000
Q 2 - The water in a rectangular supply having a base 80m by 60m is 6.5m profound. In what time can the water be purged by a channel of which the cross-area is a square of side 20 cm, if the water runs through the funnel at the rate of km every hour?
Answer : C
Explanation
Volume of water in the reservoir =(80*60*13/2)m3= 31200 m3 Volume of water flown in 1 hour = (15*1000*20/100*20/100) m3 = 600 m3 Time taken = (31200/600) = 52 hrs
Q 3 - A swimming shower is 24 m long and 15 m wide. At the point when various men jump into the shower, the tallness of water ascends by 1 cm. On the off chance that the normal volume of water uprooted by every men be 0.1 m3, what number of men arrive in the shower?
Answer : B
Explanation
Let there be x man in the bath .Then, x *0.1= (24*15*1/100) ⇒x*1/10= 24*15*1/100⇒x= 36.
Q 4 - If the zone of the three adjoining appearances of a cuboidal box is 120 cm2, 72 cm2 and 60 cm2 individually, then the volume of the crate is:
Answer : A
Explanation
Lb= 120, bh= 72 and Lh = 60 ⇒ (Lb*bh*Lh) = 120*72*60⇒ (Lbh) 2= (120*72*60) ⇒ Lbh =√ (12*10*12*6*10*6) = (12*10*6) = 720 ∴ Volume = 720 cm3
Q 5 - The region of the card board expected to make a crate size 25 cm* 15cm *8 cm will be:
Answer : B
Explanation
Area needed = 2(25*15+15*8+25*8) cm2 =2(375+120+200) cm2= 2(695) cm2 = 1390 cm2
Q 6 - The aggregate surface zone of 3D square (cube) is 1734 cm2 .Its volume is:
Answer : D
Explanation
6a2=1734 ⇒a2=289= (17) 2 ⇒a= 17 Volume = a3= (17*17*17) cm3= 4913cm3
Q 7 - The tallness of a barrel is 14 cm and its width is 10cm. The volume of the barrel is:
Answer : A
Explanation
Given h= 14cm and r= 5cm Volume = πr2h = (22/7*5*5*14) = 1100cm3
Q 8 - A divider with 10 m inside diameter is burrowed 14 m profound. Earth taken out of it is spread all around to a width of 5 m to shape a dike. The tallness of the bank is:
Answer : C
Explanation
Volume of the earth dugout = πr2h = (22/7* 5*5*14) m3= 1100m3 Area of embankment = π (R2- r2) = 22/7*[(10)2-(5)2] = (22/7*75) m2 Let the height of the embankment be h meters. Then, 22/7*75*h = 1100 ⇒h = (1100*7/22*1/75) m = 14/3 m = 4.66m
Q 9 - A chamber and a cone have the same stature and the same sweep of base. The proportion between the volumes of the barrel and the cone is:
Answer : B
Explanation
Ratio of their volume= πr2h/1/3 πr2h= 3/1 =3:1
Q 10 - If the sweep of circle is 6cm, then its volume is:
Answer : A
Explanation
Volume = {4/3π*(6)3} cm3 = (4/3π*6*6*6) cm3= (288π) cm3
