In a certain store, the profit is 320% of the cost. If the cost increases by 25% but the selling price remains constant, approximately what percentage of the selling price is the profit? | [
"120%",
"None",

Let C.P. = Rs. 100. Then, Profit = Rs.320,
S.P. = 420.
Let C.P. = Rs. 125% of Rs. 100 = Rs.125.
New S.P. = Rs.420.
Profit = Rs. (420 - 125) = Rs.295.
∴ Required percentage = (295 / 420 x 100)%

A box contains 14 pairs of shoes (28shoes in total). If two shoes are selected at random, what it is the probability that they are matching shoes? | [
"1/20",
"1/27",
"1/19",
"1/9"
] | B | The problem with your solution is that we don't choose 1 shoe from 28 but rather choose the needed one AFTER we just took one and need the second to be the pair of it. So, the probability would simply be: 1/1*1/27(as after taking one at random there are 27 shoes left and only one is the pair of the first one)=1/27

The sector of a circle has perimeter 83 cm and central angle 225o. Find its radius? | [
"28 cm",
"14 cm",
"21 cm",
"24 cm"
] | B | Let radius = x cm
Perimeter of the sector = length of the arc + 2(radius)
83= (225/360 * 2 * 22/7 * x) + 2(x)
83= 55x/14 + 2x
83 = 83x/14
