(a) 70%
(b) 72%
(c) 76%
(d) 75%
Answers:
- Answer: (a)
A = C – 4 …….(1)
B = A + 15 …….(2)
C = B – 15 …….(3)
From (1) and (3)
A = B – 11 – 4
A = B – 15
A: B: C
B – 15: B: B – 11
B – 15 + B + B – 11 = 178
3 B = 178 + 26 = 204 => B = 68
A = 53, C = 57
- Answer: (a)
Volume of cylinder = volume of sphere (Given)
pi r2 h =4/3 pi r3
h=4/3 r
4/3×6 = 8 cm
- Answer: (b)
Sum of 30 numbers = 30×40 = 1200 Sum of 40 numbers = 40 × 30 = 1200
Average of 70 numbers = (1200 +1200)/7 = 2400/7 = 34 2/ 7
