- If the volume of a sphere is numerically equal to its surface area, then its diameter is
(A) 4 unit
(B) 2 unit
(C) 3 unit
(D) 6 unit
Solution:
- Answer: (D)
225 = 3 × 3 × 5 × 5
375 = 3 × 5 × 5 × 5
450 = 2 × 3 × 3 × 5 × 5
500 = 2 × 2 × 5 × 5 × 5
LCM = 2 × 2 × 3 × 3 × 5 × 5 × 5 = 4500
HCF = 5 × 5 = 25
Difference = 4500 – 25 = 4475
- Answer: (C)
A = P[1+ R/100]^t
676/625=(1+8/(2*100))2t
2t=2
t= 1 yr
- Answer: (B)
Let the numbers be 7x and 12x, respectively.
According to the question, 12x = 7x + 25
5x = 25
x = 25/5 = 5
Therefore, numbers are 35 and 60 Product of numbers = 35 × 60 = 2100
- Answer: (C)
After dividing 32642 by 112, we get 50 as remainder.
∴The least number which must be added to 32642 to make it divisible by 112 is (112 – 50) = 62.
- Answer: {B}
Let the common ratio of the ratio be ‘k’.
Sum of angles of a triangle is 180.
So, 2k + 3k + 7k = 180 k = 15
So, the angles are 30, 45 and 105. Thus the triangle is obtuse angled.
- Answer: D
(x+y)2= x2+y2+2xy=49xy
x/y+y/x=(x2+y2)/xy=(49xy-2xy)/xy=47
- Answer: (B)
Cost price of the machine for the businessman including repair = 15000 + 1000 = 16000
Selling price of machine = 20,000
Profit = S.P – C.P = 20,000 – 16,000 = 4000
Profit% = profit/C P*100 = (4000/16000)*100 = 25%
- Answer: (A)
According to the question, Let supplementary angles be x and 180° – x.
180°-x -x = 44°
180°-2x = 44°
x = (180-44)/2=136/2 = 68°
- Answer: (B)
(p2) 2+ k + 2 (9) p2 If k = 92; (p2) 2+ k + 2 (9) p2 = (p2 + 9)2
Therefore, for k = 92; p4 + k + 18p2 will be a perfect square.
- Answer: (D)
Let radius of sphere = r unit
Then, 4/3 (πr3) = 4πr2⇒ r = 3 unit
So diameter = 2r = 6 unit
