Correct Answer: 1/42
Explanation:
Required probability = 6!5!/10! = 1/42
Correct Answer: ? 50
Explanation:
SP = 125% of CP [? SP = {(100 + Gain%)/100} x CP]
= {125/100} x 40
= (5/4) x 40 = 5 x 10 = ? 50
Correct Answer: Z decreases
Explanation:
The profit = SP - CP
If SP and CP both increase at same amount then the profit would be same.
As we know profit % (Z) = Actual profit / CP
So if CP increases the profit % (Z) will go down as there is no change in actual profit.
Correct Answer: 32
Explanation:
Required number = 80 - 60% of 80
= 80 - (60 x 80)/100
= 32
Correct Answer: 3
Explanation:
As per the given above equations , we can say that
?.
?500x + ?402 = 0
? ?500x = - ?402
? x = - ?( 402/500 ) = - ?( 400/500 ) = - 0.9
?. ?360y + ( 200 )1/2 = 0
? ?360y = - ?200
?
y = - ?( 200 / 360 ) = - 0.74
Clearly, we can see that x < y is required answer .
Correct Answer: 12%
Explanation:
Let sum = Rs. P.
Then amount = Rs. (8P/5)
? S.I = Rs. (8P/5 - P ) = Rs.(3P/5)
? Required rate = (100 x SI) / (P x T)
= [(100 x 3P/5) / (P x 5)]% = 12%
Correct Answer: 4%
Explanation:
? S.I. for 3/2 years = Rs. (1067.20 - 1012) = Rs. 55.20
? S.I. for 5/2 years = Rs. 55.20 x (2/3) x (5/2) = 92
? Sum = Rs. (1012 - 92) = Rs.920
Hence, Rate = (100 x SI)/(P x T) = (100 x 92) / (920 x 5/2 ) = 4%
Correct Answer: 8 years 4 months
Explanation:
Let principal = P.
Then, S.I = P,
Rate (R) = 12%
Time = (100 x SI) / (R x P) = (100 x P) / (P x 12) years
= 25/3 years
= 8 years 4 months
Correct Answer: Data inadequate
Explanation:
Let, Sum = P
Then S.I = P/2
Rate = 8%
and Time = 6 years
But P/2 = (P x 8 x 6) /100 (Not possible )
Thus, data is inadequate.
Correct Answer: 6310
Explanation:
? = 6888.009 - 487.999 - 87.989
? ? ? 6888 - 488 - 88
? ? ? 6888 - 576 ? ? ? 6312 ? 6310
