A retailer sells 7 shirts. The first 2 he sells for $38 and $42. If the retailer wishes to sell the 7 shirts for an overall average price of over $50, what must be the minimum average price of the remaining 5 shirts? | [
"$57.00",
"$60.50",
"$54.00",
"$63.00"
] | C | First 2 shirts are sold for $38 and $42=$80.
To get average price of $50,total sale should be 7*$50=$350
So remaining 5 shirts to be sold for $350-$80=$270
Answer should be 270/5=$54.00 that is A | AquaRat_train |
A shopkeeper sold an book offering a discount of 5% and earned a profit of 25%. What would have been the percentage of profit earned if no discount was offered? | [
"131.6",
"120",
"130",
"150"
] | A | Let C.P. be $100.
Then, S.P. = $125
Let marked price be $x. Then, 95/100 x = 125
x = 12500/95 = $131.6
Now, S.P. = $131.6, C.P. = $100
Profit % = 31.6%.

If a company sells a car with a marked price of Rs. 5,40,000 and gives a discount of 5% on Rs. 3,00,000 and 3% on the remaining amount of Rs. 2,40,000, then the actual price charged by the company for the car is : | [
"Rs.5,17,800",
"Rs.5,10,560",
"Rs.5,20,000",
"Rs.5,10,100"
