A man can row with a speed of 15 kmph in still water. If the stream flows at 5 kmph, then the speed in downstream is________?
A. 10 kmph
B. 5 kmph
C. 20 kmph
D. 22 kmph
Explanation:
M = 15
S = 5
DS = 15 + 5 = 20
A. 10 kmph
B. 5 kmph
C. 20 kmph
D. 22 kmph
Explanation:
M = 15
S = 5
DS = 15 + 5 = 20
A. 5 km
B. 5.5 km
C. 6 km
D. 6.5 km
Average speed = ( 2 X 3 X 2/3 + 2 ) km/ hr = 12/5 km/ hr. Distance travelled = ( 12/5 X 5 )km = 12 km. So Distance between house and school = ( 12/2 )km = 6 km.
A. 35.4 cm
B. 32.4 cm
C. 32 cm
D. 30 cm
A. Rs. 112
B. Rs. 118.80
C. Rs. 120
D. Rs. 122
A. 25%
B. 50%
C. 75%
D. 33%
Explanation:
(?% /100) * 120 = 90
? = 75%
A. Rs.18,828.80
B. Rs.19,828.80
C. Rs.18,028.80
D. Rs.17,828.80
E. None of these
Explanation:
Let the sum be Rs.P
P{ [ 1 + 8/100]2 – 1 } = 2828.80
P(8/100)(2 + 8/100) = 2828.80 [a2 – b2 = (a – b) ( a + b)] P = 2828.80 / (0.08)(2.08) = 1360/0.08 = 17000 Principal + Interest = Rs. 19828.80
A. Success rate is higher for women
B. Overall success rate is below 50%
C. More men cleared the examination than women
D. Both ‘A’ and ‘B’
Explanation:
Let there are 100 persons in which 60 men and 40 women number of men who cleared the qualifying test
= 70 x 60/100 = 42
Number of women who cleared the qualifying test
= 40 x ¾ = 30
Number of men who get success in final test
= 42 x 4/5 = 33.6
Number of women who get success in final test
= 30 x 70/100 = 21
Hence more men cleared the examination than a woman.
