Given the current price of 2 mangoes is tk. 12, the current cost of one mango is:
12/2=tk. 6
thus the cost of 50 mangoes will be:
Total price=(number of mangoes)*(cost of each mango)
=50*6
=300
The cost of 50 mangoes is tk. 300

Answer:
A = 64 pi
or approximately 200.96
Step-by-step explanation:
The diameter is twice the radius
d = 2r
16 = 2r
Divide by 2
16/2 = 2r/2
8 =r
The area of a circle is
A = pi *r^2
A = pi*(8)^2
= pi *64
Or if we approximate pi as 3.14
A = (3.14) * (64)
A = 200.96

Answer:
Sample size is
Step-by-step explanation:
Given that,
Margin of error %
Confidence level %
Suppose, sample proportion
i.e.
We know that,
Margin of error
∴
squaring on both side,
∴
Hence, the sample size is,
Hence, the correct option is
