Correct Answer: 3 months
Explanation:
S.I. on Rs. 1600 is P.W. of Rs. 1624
i.e. Rs. 24 is the S.I. on Rs. 1600 at 6%
? Time = (100 x 24) / (1600 x 6) = 1/4 year = 3 months
Correct Answer: 31 / 3%
Explanation:
B.D. for 3/2 years = Rs. 60
B.D. for 2 years = Rs. (60 x 2) / (3 x 2) = Rs. 80
Now, B.D. = Rs. 80, T.D. = Rs. 75 and Time = 2 years.
? Sum = Rs. (80 x 75) / 5 = Rs. 1200
? Rs. 80 is S.I. Rs. 1200 for 2 years.
So, rate = (100 x 80) / (1200 x 2)% = 31/3%
Correct Answer: 6 : 3 : 2
Correct Answer: ? 72
Explanation:
Given that PW = ? 576 , BG = ? 9 and TD = ?
TD = PW x BG
= 576 x 9
= 24 x 3
= ? 72
Correct Answer: 200, 360,160
Explanation:
let ratio be x.
Hence no. of coins be 5x ,9x , 4x respectively
Now given total amount = Rs.206
=> (.50)(5x) + (.25)(9x) + (.10)(4x) = 206
we get x = 40
=> No. of 50p coins = 200
=> No. of 25p coins = 360
=> No. of 10p coins = 160
Correct Answer: 1.20
Explanation:
(x * 5) = (0.75 *8)
X=6/5 = 1.20
Correct Answer: 600
Explanation:
1/2:1/3:1/4 = 6:4:3
As the difference is 3
