Correct answer is: Rs.19,488

Explanation:

Selling price (S.P.) of 12 mobile phones = Rs. 188,160

Cost price (C.P.) of 12 mobile phones = 12 × 14056 = Rs. 168,672

Total profit = S.P. – C.P = 188160 – 168672 = Rs. 19,488

∴ Total profit made by her = Rs. 19,488

Correct answer is: 25% Profit

Explanation:

Cost price (C.P.) of 5 cars = Selling price (S.P.) of 4 cars

⇒ Gain = C.P. of 1 car

Profit% = [Gain/C.P.]× 100 = [1/4] × 100 = 25%

∴ Profit% = 25%

Correct answer is: 46

Explanation:

Let us assume the digits are x and y, so the number is written as "xy".

Sum of digits is 10, so

x + y = 10 ..........................(1)

as x is in 10s' place and y in units place the actual number is 10*x + y

when the digits are interchange (i.e number written as "yx") the actual number becomes 10*y+x

Given that interchanging increases the value by 18, so

(10*y+x) - (10*x + y) = 18

i.e 9*y - 9*x = 18

i.e y - x = 2 ............................. (2)

Adding (1) and (2) we get

2*y = 12

or y =6

Putting y = 6 in (1)

x + 6 = 10

or x =4

So the number is 10*x + y

i .e 10 * 4 + 6

or 46

Correct answer is: 195

Explanation:

COW denotes a 3 digit number .

CW denotes a two digit number .

$\frac{COW }{ CW} = 13 ,$

COW = 13 CW

From options , A ---> 272

22 x 13 = 286 not equal to 272

From Option B ---> 195

15 x 13 = 195 equal to given option
