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
