__Solution:__**1).**Maked price = [100 / (100 – 7.5)] × 740

= (740 × 100) / 92.5 = Rs. 800

**Answer: c )**

**2).**Single equivalent discount = { 25 + 5 – [(25 × 5) / 100] }%

= (30 – 1.25)% = 28.75%

**Answer: a)**

**3).**Let the cost price be Rs. 100 and marked price be Rs. x

∴ (x × 90) / 100 = 108

9x / 10 = 108

x = (108 × 10) / 9 =120

∴Required percentage = 20%

**Answer: d)**

**4).**

Mixture
– I Mixture – II

4/7 2/5

1/2

(1/2)-(2/5)
4/7 – 1/2

=
(5 – 4) / 10 = 1 / 10 = (8 – 7)
/ 14 = 1 / 14

∴Required
ratio = 1/10 : 1/14 = 7 : 5

**Answer: a )**

**5).**Sumit’s present age = 2x years

Prakash’s present age = 3x years

∴ 3x – 2x =6

x= 6

∴Required ratio = ( 2 × 6 + 6) : (3 ×
6 + 6)

= 18 : 24

= 3 : 4

**Answer: d )**

**6).**Milk : Water = K : 1

∴ S.P. = (K +1) × 9

C.P. = 10 K

Gain = 9 – K

Gain% = [(9 – K) / 10K ] × 100

[(9 – K) / 10K ] × 100 = 20

90 – 10K = 20K

30K = 90

K = 3

∴ Ratio = 3 : 1

**Answer: a)**

**7).**Sum of the ages of two new persons

= 30 + 34 + 3 × 8

= 88 years

∴Required average

88 / 2 = 44 years

**Answer: d)**

**8).**Sum of the present ages of 10 members

= 20 × 10 = 200 years

Total age of 9 members 10 years ago
= 100 years

∴Required average = 100 / 9 = 11 (1
/ 9 ) years

**Answer: d )**

**9).**x + x + 2 + x + 4 + x + 6

= 15 × 4

4x + 12 =60

4x = 60 – 12 = 48

x = 48 / 4 = 12

**Answer: d )**

**10).**C.P, of first chair

= (100 / 125) × 120 = Rs. 96

C.P, of second chair

= (100 / 75) × 120 = Rs. 160

∴
Loss = 160 + 96 – 240 = Rs.16
