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

Answer:
a² + 4a + 4
Step-by-step explanation:
(a + 2) ² = (a + 2) ( a + 2)
= a ( a + 2) + 2 ( a + 2)
= a² + 2a + 2a + 4
= a² + 4a + 4
