5%.

Solution: cost = x
186 + 0.07x = x
x = Rs. 200

Selling at 210
Profit = (210 - 200) / 200 = 5%

Answer2 90
(1/9) - (1/10) = 1/90
Answer = 90 hrs

(4*16)/8 = 8 hrs

If you dont mind i want to correct some of these

X + 30-6 = 3X.........Eq. (1)

X + 24 = 3X
3X - X = 24
2X = 24
X = 12
Put the value of X in Eq (1)
Now
12+30-6 = 3(12)
36 = 36
so
I think Mr. Shoukat bought originally 12 oranges

4. If a man were to sell his horse for Rs.720, he would lose 25%. What must he sell it for to gain 25% ?
Solution:
selling price + lose = cost
720 + 25%c = c
cost = 960
he wants profit of 25%.
Selling price = 960 * 1.25 = 1,200



But 25% of 720 is 180 not 240.. so it becomes 900 not 960... please correct me if i am wrong
