A. 18 3/4 %
B. 20 %
C. 16 3/4 %
D. 19 %
Explanation:
Required % = (9/48 × 100)% = 75/4 % = 18 ¾ %
A. 10%
B. 8%
C. 5%
D. 6%
Explanation:
C.P = Rs. 100.
Then marked price = Rs. 120
S.P = 90% of Rs. 120 = Rs. 108
Gain = 8%
A. 40 degrees
B. 38 degrees
C. 36 degrees
D. 34 degrees
M + Tu + W + Th = 4 * 48 = 192
Tu + W + Th + F = 4 * 46 = 184
M = 42
Tu + W + Th = 192 -42 = 150
F = 184 – 150 = 34
A. 60
B. 64
C. 72
D. 80
Explanation:
Given M + P + C = 80 * 3 = 240 — (1)
M + P = 90 * 2 = 180 — (2)
P + C = 70 * 2 = 140 — (3)
Where M, P and C are marks obtained by the student in Mathematics, Physics and Chemistry.
P = (2) + (3) – (1) = 180 + 140 – 240 = 80
A. 8
B. 6
C. 4
D. 2
Work done by P in 1 day = 1/18
Work done by Q in 1 day = 1/15
Work done by Q in 10 days = 10/15 = 2/3
Remaining work = 1 – 2/3 = 1/3
Number of days in which P can finish the remaining work = (1/3) / (1/18) = 6
A. 36
B. 81
C. 91
D. 116
Explanation:
When the dice are rolled, the number of possible outcomes = 63 = 216.
Number of possible outcomes in which 2 does not appear on any dice = 53 = 125.
Therefore, Number of possible outcomes in which at least one dice shows 2 = 216- 125 = 91.
