Correct Answer: Rs.32
Correct Answer: 5%
Correct Answer: Rs. 7500
Explanation:
Let the sum invested be x.
? 8x/100 + 12x/100 = 1500
? 20x = 150000
? x = 7500
Correct Answer: 6 times
Explanation:
A = P(1 + rt/100)
So, A= 3P (it becomes triples)
3P = P(1 + 8r/100)?r = 25%
Now, when t = 20
?A = P(1 + 25*20/100)
?A = P(1+ 5)?A = 6P
So, it becomes 6 times.
Correct Answer: 11,250
Explanation:
SI = PTR/100
SI = PX100/100
SI = P
So, Amount=P+SI=2P?22500 = 2P?P = 11250
Correct Answer: 40000
Correct Answer: 13
Correct Answer: 4000
Correct Answer: 500
Correct Answer: Rs. 4,000
Explanation:
Let sum invested @ 5% be P1, @ 6% be P2 then @ 9% =17200-(P1+P2)
So according to question
P1*5*2/100 = P2*6*2/100 or P1 = (6/5) P2
Also P2*6*2/100 = [17200-(P1+P2)]*9*2/100
Or 2 P2 = [17200?(11/5)P2] * 3
Or (2 + 33/5)P2 = 17200 * 3
P2 = 17200 * 3 * 5 / 43 = 6000
So P1 = 6/5 P2 = 7200
So Sum invested @ 9% = 17200?(6000+7200) = Rs 4000
