7200 Kilometers in two hours. 4,320 kilometers in 6 hours.
Answer:
Rs. 42000
Step-by-step explanation:
Let us assume that Mr. Ahmed bought the bicycle for Rs. x, and sold it for Rs. y to Mr. Saad. Since he made a loss of 28%, hence:
y = x - 0.28x = 0.72x
Mr. Saad spent Rs.1680 on its repairs, therefore the total cost price of the motorcycle = 0.72x + 1680
He then sold it for Rs.35910 making a profit of 12.5%. Therefore:
0.72x + 1680 + [0.125(0.72x + 1680)] = 35910
0.81x + 1890 = 35910
0.81x = 34020
x = Rs. 42000
Therefore the cost price of the motorcycle for Mr. Ahmed is Rs. 42000
The answer to the first question is b
I don’t know the answer to the second one sorry
-1/2p + 4 < 3
-1/2p < 3 - 4
-1/2p < -1
-p < (-1 x 2)
-p < -2
p > -2/-1
p > 2
