A. 1400
B. 1300
C. 1200
D. 1100
Explanation:
CP* (76/100) = 912
CP= 12 * 100 => CP = 1200
A. 200cm
B. 175cm
C. 125cm
D. 150cm
A. 8km/hr
B. 12km/hr
C. 14 km/hr
D. 15 km/hr
E. None of these
Explanation:
Speed downstream = (30 x 2/5)km/hr = 12km/hr
Speed upstream = (30 x 4/15) km/hr = 8 km/hr
Speed of boat in still water = ½ (12 + 8)km/hr = 10 km/hr
A. 9985
B. 9960
C. 9957
D. 9975
Explanation:
Greatest 4-digit number is 9999. LCM of 3, 4 and 5 is 60. Dividing 9999 with 60, we get remainder 39. Thus, the required number is 9999 – 39 = 9960.
A. 18% p.a.
B. 22% p.a.
C. 20% p.a.
D. 24% p.a.
E. None of these.
Explanation:
Rs.1440 – 1200 = Rs.240 is the interest on Rs.1200 for one year.
Rate of interest = (100 * 240) / (100 * 1) = 20% p.a
A. 10%
B. 10.5%
C. 12%
D. None of these
Explanation:
Difference in C.I. and S.I for 2 years = (696.30 – 660) = Rs. 36.30.
S.I for one year = Rs. 330.
S.I. on Rs. 330 for 1 year = Rs. 36.30
Rate = (100 * 36.30)/(330 * 1) = 11%
A. One
B. Zero
C. Three
D. Cannot be determined
Explanation:
We cannot predicted the number of dinners that the particular number has to host in one year.
