A. 5 %
B. 10 %
C. 15 %
D. 20 %
Explanation:
P be the principle and R % Per annum be the rate.
P(1 + R/100) 3 = 10648 – (i)
P(1 + R/100) 2 = 9680 – (ii)
By dividing (i) and (ii)
(1 +R/100) = 10648/9680 Or
R/100 = 968/9680 = 1/10 or
R = 10 %
A. 33
B. 44
C. 55
D. 66
Explanation:
Average = (11 + 22 + 33 + 44 + 55 + 66 + 77 + 88 + 99)/9
= [(11 + 99) + (22 + 88) + (33 + 77) + (44 + 66) + 55]/9
= [(4 * 110) + 55]/9 = 495/9 = 55
A. 6 hrs 21 min
B. 6 hrs 24 min
C. 6 hrs 27 min
D. 6 hrs 30 min
Time taken to cover 600 km = ( 600/100 ) hrs = 6 hrs. Number of stoppages = ( 600/75 – 1 ) = 7 Total time of stoppage = (3 x 7) min = 21 min. Hence, total time taken = 6 hrs 21 min.
