Let the costs of each kg of apples and each kg of rice be Rs.a and Rs.r respectively.
10a = 24r and 6 * 20.50 = 2r
a = 12/5 r and r = 61.5
a = 147.6
Required total cost = 4 * 147.6 + 3 * 61.5 + 5 * 20.5
= 590.4 + 184.5 + 102.5 = Rs.877.40
A. Rs 17423
B. Rs 18973
C. Rs 19448
D. Rs 19880
Explanation:
P = Rs 16000, R = (10/2)%
Per half-year , t= 4 half-years
Therefore Amount = Rs [16000 × (1+5/100)4]
= Rs (16000 × 21/20 × 21/20 × 21/20 × 21/20)
= Rs 1448.10 ~ Rs 19448
A. 150 m
B. 125 m
C. 130 m
D. 100 m
Explanation:
A can give B (5 min – 4 1/2 min) = 30 sec start.
The distance covered by B in 5 min = 1000 m.
Distance covered in 30 sec = (1000 * 30)/300 = 100 m.
A can give B 100m start.
A. 196
B. 630
C. 1260
D. 2520
Explanation:
L.C.M of 12, 18, 21, 30
