6. 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^3
   1275 cm^3
   1111 cm^3
   1176 cm^3
   1075 cm^3
   Option 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

    

7. 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%

    

8. 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.
   3
   6
   5
   1
   2
   Option C
   [10(x+5)+200] /(x+10) = 2*10
   => x = 5

    

9. 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.
   4
   2
   5
   6
   3
   Option E
   Ratio of Profit = A:B:C
   = (1*12):[2x+1*(12-x)]: (3*12)
   => 36/[12+12+x+36] = 2400/4200
   => x = 3

    

10. 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.
    55
    60
    62
    78
    70
    Option 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
