Nithin ? undefined
Correct answer is: Rs. 6160
Explanation:
\(\eqalign{ & {\text{C}}{\text{.P}}{\text{. = Rs}}{\text{. 4900}}{\text{.}} \cr & {\text{S}}{\text{.P}}{\text{. = 110}}\% {\text{ of Rs}}{\text{.4900}} \cr & {\text{ = Rs}}{\text{.}}\left( {\frac{{110}}{{100}} \times 4900} \right) \cr & = {\text{Rs}}{\text{. 5390}}{\text{.}} \cr & {\text{Let marked price be Rs}}{\text{.}}x \cr & {\text{Then,}} \cr & {\text{ = 87}}\frac{1}{2}\% {\text{ of }}x{\text{ = 5390}} \cr & \Rightarrow \left( {\frac{{175}}{2} \times \frac{1}{{100}} \times x} \right) = 5390 \cr & \Rightarrow x = \left( {\frac{{5390 \times 8}}{7}} \right) = 6160 \cr & \therefore {\text{Marked price}} = {\text{Rs}}{\text{.6160}} \cr}\)
A book is listed at Rs. 150, with a discount of 20 per cent. What additional discount must be offered to bring the net price to Rs. 108 ?
Nithin ? undefined
Correct answer is: None of these
Explanation:
Selling price after given 20% discount
\(\eqalign{ & = 150 \times \frac{{\left( {100 - 20} \right)}}{{100}} \cr & = 120 \cr & {\text{So,}} \cr & \Rightarrow 120 \times \frac{x}{{100}} = 108 \cr & \Rightarrow x = 90 \cr}\)
∴ Required additional discount = (100 - 90)% = 10%
On a Rs. 10000 payment order, a person has choice between 3 successive discounts of 10%, 10% and 30%, and 3 successive discounts of 40%, 5% and 5%. By choosing the better one he can save (in rupees)
Nithin ? undefined
Correct answer is: 255
Explanation:
Final price in 1st case
= 70% of 90% of 90% of Rs. 10000\(\eqalign{ & = {\text{Rs}}{\text{.}}\left( {\frac{{70}}{{100}} \times \frac{{90}}{{100}} \times \frac{{90}}{{100}} \times 10000} \right) \cr & = {\text{Rs}}{\text{. 5670}}{\text{}} \cr}\)
Final price in 2nd case
= 95% of 95% of 60% of Rs. 10000\(\eqalign{ & = {\text{Rs}}{\text{.}}\left( {\frac{{95}}{{100}} \times \frac{{95}}{{100}} \times \frac{{60}}{{100}} \times 10000} \right) \cr & = {\text{Rs}}{\text{. 5415}}{\text{}} \cr}\)
∴ Money saved by choosing the better offer
= Rs. (5670 - 5415)
= Rs. 255
The labelled price of a cupboard is Rs.6,500/-. The shopkeeper sold it by giving 5% discount on the labelled price and earned a profit of 15%. What approximately is the cost price of the cupboard?
Nithin ? undefined
Correct answer is: Rs.5,350/-
Explanation:
According to question
Selling Price\(= \text{Rs. }6500 - \text{Rs. }\frac{6500 \times 5}{100}\)
= Rs.6500 - Rs.325 = Rs.6175
Therefore, Cost Price = Rs. \( \frac{6175 \times 85}{100}\)
=Rs.5248.75
=Rs.5350
A company decided to sell Rs.50.000/- T.V. set for Rs.46,000/ as a world cup offer. What is the percentage discount offered by the company?
Nithin ? undefined
Correct answer is: 8%
Explanation:
Required percentage discount
\(= \frac{ \left(50000-46000\right) }{50000} \times 100\)\(= \frac{4}{50} \times 100\)
= 8%
A shopkeeper sold a T.V. set for Rs.17.940/-, with a discount of 8% and gained 19.6% if no discount is allowed, what will be his gain per cent?
Nithin ? undefined
Correct answer is: None of these
Explanation:
Discount = 8% & S.P.. = Rs.17,940
Therefore, M.P. = \(\frac{17940}{0.92}\) = Rs.19500
Now, gain % = 19.6%
\(\implies \text{ C.P. }= \frac{17940}{1196} = \text{Rs 15000}\)
= Rs.4500
Hence gain % = \(\frac{4500}{15000} \times 100\) = 30%
