Correct answer is: Rs.105
Explanation:
Ratio of the investment = 35:45:55
\(\implies 7:9:11\)
\(\therefore \text{P's } share = \frac{7}{27} \times 405 = \frac{2835}{27} = 105\)
= Rs. 105
A coconut merchant find that the cost price of 2750 coconut is the same as the selling price of 2500 coconuts. The percentage loss or gain is
prakash ? Dec 16 '2019 at 21:56
Correct answer: 10% gain
Explanation:
According to question,
2750 CP = 2500 SP
\(\frac{CP}{SP}=\frac{2500}{2750}=\frac{10}{11}>1 \) unit profit\(\text{profit} \% = \frac{1}{10} \times 100 = 10 \% \text{ gain}\)
If x is less than y by 25%, then y exceed x by....
rahul ? Jan 11 '2020 at 17:50
Correct answer is : \(33 \frac{1}{3} \%\)
Explanation:
Let us assume y =100, so according to question X is less than y by 25 % , so x =75,
\(\text{Hence y exceed x by =} \frac{25}{75} \times 100 = 33.33 % or 33 1/3 \text{ %}\)
A student multiplying a number by $\frac{3}{5}$ instead of $\frac{5}{3}$, what is percentage error in the calculation?
suraj ? Dec 17 '2019 at 21:37
Correct answer is: 0.64
Explanation:
Let the number be x.
Then, ideally he should have multiplied by x by \(\frac{5}{3}\). Hence Correct result was \(x \times \frac{5}{3}= \frac{5x}{3}\).
By mistake he multiplied x by \(\frac{3}{5}\) . Hence the result with error = \(\frac{3x}{5} \)
Then, error = \(\big(\frac{5x}{3} - \frac{3x}{5}\big) = \frac{16x}{15} \)
\(\text{Error} = \big(\frac{\text{error}}{\text{True vaue}}\big) \)
= \(\frac{\frac{16}{15} \times x}{ \frac{5}{3} \times x} \)
= 0.64
