(c) 9 : 40
(d) 20 : 9
Answer- 1
4l : 900 mL,
= 4000 mL : 900 mL,
= 4000 : 900,
= 40 : 9
Question -2 When the number 210 is increased in the ratio 5 : 7, the the new number is
(a) 150
(b) 180
(c) 294
(d) 420
Answer -2
210 is increased in the ratio 5 : 7, then
New increased number will be = 210 × 7/5
= 294
Question-3 Two numbers are in the ratio 7 : 9. If the sum of the numbers is 288, then the smaller number is
(a) 126
(b) 162
(c) 112
(d) 144
Answer -3
Ratio in two number = 7 : 9
Sum of numbers = 288
Sum of ratios = 7 + 9 = 16
Smaller number = (288 × 7)/16
= 126
Question -4 The ratio of number of edges of a cube to the number of its faces is
(a) 2 : 1
(b) 1 : 2
(c) 3 : 8
(d) 8 : 3
Answer -4
No. of edges of the cube = 12
No. of faces = 6
Ratio in edges a cube to the number of faces = 12 : 6
= 2 : 1
Question-5 If x, 12, 8 and 32 are in proportion, then the value of x is
(a) 6
(b) 4
(c) 3
(d) 2
Answer-5
x, 12, 8, 32 are in proportion, then
x × 32 = 12 × 8 (∵ ad = bc)
⇒ x = (12 × 8)/32 = 3
x = 3
Question-6 The fourth proportional to 3, 4, 5 is
(a) 6
(b) 20/3
(c) 15/4
(d) 12/3
Answer-6
The fourth proportion to 3, 4, 5 will be
= (4 × 5)/3
= 20/3
Question-7 The third proportional to 25/4 and 5 is
(a) 4
(b) 17/2
(c) 3
(d) none of these
Answer-7
The third proportional to 6.1/4 and 5 is
⇒ 6. 1/4 : 5 : : 5 : x
⇒ 25/4 : 5 : : 5 : x
⇒ x = {(5 × 5)/25} × 4,
⇒ 4
Question-8 The mean proportional between 1/2 and 128 is
(a) 64
(b) 32
(c) 16
(d) 8
Answer-8
The mean proportional between 1/2 and 128 is
