? = 19 - Find the volume of a cone of slant height 25 cm whose curved surface area is same as that of a cylinder of radius 8.75 cm and height 10 cm.
1205 cm^31275 cm^31111 cm^31176 cm^31075 cm^3Option D

CSA of cone = CSA of cylinder

25*pi*r = 2*pi*8.75*10

=> r = 7 cm

H^2 = 25^2 – 7^2

=> H = 24 cm

Volume of cone = 1/3*pi*r *r*h

= 1/3*3*7*7*24 = 1176 cm^3 - A shopkeeper sold a book for Rs. 420 at some profit. Had he sold the book for Rs. 17.5 more, he would have earned 5% more profit. Find the profit% earned by the shopkeeper initially.
10%40%30%50%20%Option E

Let CP be Rs. X

Initailly Profit% be y%.

x*(y+100)/100 = 420 —–(1)

x*(y+100+5)/100 = (420+17.5) ——(2)

On solving (1) and (2) , we get

x = Rs. 350

y = 20% - The average weight of (x+5) eggs is 10 grams. If 5 more eggs are added then the average gets doubled. Find the value of x, if the 5 eggs which are added weigh 200 grams.
36512Option C

[10(x+5)+200] /(x+10) = 2*10

=> x = 5 - A,B and C start a business together with ratio of investment as 1:2:3 resp. After x months, A withdrew half of his investment. After a year, C received Rs. 2400 as profit out of a total profit of Rs. 4200. Find the value of x.
42563Option E

Ratio of Profit = A:B:C

= (1*12):[2x+1*(12-x)]: (3*12)

=> 36/[12+12+x+36] = 2400/4200

=> x = 3 - There are 2400 students in a school and the ratio of girls and boys is 3:5 resp. (x+2)% of boys and (x-3)% of girls passed in their annual examination. Find the value of x, if 78.125% of students passed in the examination.
5560627870Option D

Girls = 3/(3+5)*2400 = 900

Boys = 2400 – 900 = 1500

(x+2)% of 1500 + (x-3)% of 900 = 78.125% of 2400

=> x = 78
