C. 1700
D. 2000
A. 300 km
B. 290 km
C. 250 km
D. 240 km
Total distance = (120*2) + (100*(1/2)) = 290 km
A. Rs. 16500
B. Rs. 15525
C. Rs. 17000
D. Rs. 17600
E. None of these
Explanation:
Price at which the TV set is bought = Rs. 12,500
Discount offered = 20%
Marked Price = 12500 * 100/80 = Rs. 15625
The total amount spent on transport and installation = 125 + 250 = Rs. 375Total price of TV set = 15625 + 375 = Rs. 16000
The price at which the TV should be sold to get a profit of 10% if no discount was offered = 16000 * 110/100 = Rs. 17600
A. 1
B. 14
C. 20
D. 21
Clearly, the numbers which have 1 or 9 in the unit’s digit, have squares that end in the digit 1. Such numbers from 1 to 70 are 1, 9, 11, 19, 21, 29, 31, 39, 41, 49, 51, 59, 61, 69.
Number of such numbers = 14.
Required percentage = (14/70 * 100) = 20%
A. 1000 kg
B. 1100 kg
C. 1125 kg
D. 1225 kg
Explanation:
Let the weight of fresh grapes be x kg
Quantity of water in it = (80/100 × x)kg = 4x/5 kg
Quantity of pulp in it = (x – 4x/5)kg = x/5 kg
Quantity of water in 250 kg dry grapes
= (10/100 × 250)kg = 25kg
Quantity of pulp in it = (250 – 25)kg = 225 kg
Therefore, x/5 = 225
=> x = 1125
A. 8: 1
B. 2√2 : 1
C. 2 : 1
D. None of these
Explanation:
Volumes be 8×3 and x3
2x and x respectively
Therefore, Ratio of their edges = 2 : 1
A. Rs. 3096
B. Rs. 4076
C. Rs. 4085
D. Rs. 4096
Explanation:
Principal = [4913 / (1 + 25/(4 * 100))3]
= 4913 * 16/17 * 16/17 * 16/17 = Rs. 4096.
