A. 12 sq m
B. 4√14 sq m
C. 20 sq m
D. 15 sq m
A. 10%
B. 10.25%
C. 10.50%
D. None of these
Let the sum be Rs. 100. Then, S.I. for first 6 months = Rs. ( 100 X 10 X 1/100 X 2 ) = Rs. 5. S.I. for last 6 months = Rs. ( 105 X 10 X 1/100 X 2 ) = Rs. 5.25. So, amount at the end of 1 year=Rs.(100 + 5 + 5.25) = Rs. 110.25 Effective rate = (110.25 – 100) = 10.25%.
A. 1 kmph
B. 5 kmph
C. 8 kmph
D. 3 kmph
Explanation:
DS = 6
US = 4
S = ?
S = (6 – 4)/2 = 1 kmph
A. 40
B. 44
C. 48
D. 52
Explanation:
Let the capacity of the can be T litres.
Quantity of milk in the mixture before adding milk = 4/9 (T – 8)
After adding milk, quantity of milk in the mixture = 6/11 T.
6T/11 – 8 = 4/9(T – 8)
10T = 792 – 352 => T = 44.
A. 480 sq.m
B. 320 sq.m
C. 600√15 sq.m
D. 450√15
A. 1 17/38
B. 1 38/17
C. 2 38/17
D. None of these
Explanation:
[(62.25/2.5) + (12.5/0.5)] / [(0.75 * 9) + (3.5 * 3.5)]
= [(6225/250) + (125/5)] / (6.75 + 12.25)
= (249/10 + 25) / 19 = 499/190 = 2 119/190
A. 6:8
B. 3:7
C. 5:4
D. 4:3
If the ratio of the speeds of two objects is a:b, then the time taken by them to cover the same distance is
b:a Hence, the answer is 4:3
