Question 6 of 10
6. Question
1 pointsCategory: Quantitative AptitudeA cone of height 7cm and base radius 1cm is carved from a cuboidal block of wood 10cm * 5cm * 2cm. Find the percentage of wood wasted in this process? [Assuming π=22/7]
Correct
Answer – 1) 278/3%
Explanation:
Volume of cone= 1/3πr^{2}h
= 1/3 * 22/7 * (1)^{2} * 7
= 22/3 cm^{3}
Volume of cubical block= 10 * 5 * 2= 100cm^{3}
Wastage of wood= (100(22/3))
= (30022)/3
= 278/3 cm^{3}
% wood= (278/3)/100 * 100%
= 278/3%Incorrect
Answer – 1) 278/3%
Explanation:
Volume of cone= 1/3πr^{2}h
= 1/3 * 22/7 * (1)^{2} * 7
= 22/3 cm^{3}
Volume of cubical block= 10 * 5 * 2= 100cm^{3}
Wastage of wood= (100(22/3))
= (30022)/3
= 278/3 cm^{3}
% wood= (278/3)/100 * 100%
= 278/3% 
Question 7 of 10

R2= 25/2%
Let the principal = P
According to question,
(P*15*15)/12*2*100 – (P*25*8)/12*2*100 = 32.50
225P/2400 – 200P/2400 = 32.50
25P/2400 = 32.50
P = Rs 3120Incorrect
Answer – 3) 3120
Explanation:
T1= 15 months= 15/12 years
R1= 15/2%
T2= 8 months= 8/12 years
R2= 25/2%
Let the principal = P
According to question,
(P*15*15)/12*2*100 – (P*25*8)/12*2*100 = 32.50
225P/2400 – 200P/2400 = 32.50
25P/2400 = 32.50
P = Rs 3120
