300221 Directions: In the following questions, the Assertions (A) and Reason(s) (R) have been put forward. Read both the statements carefully and choose the correct alternative from the following:
Assertion: The mean of the numbers 10, 20, 30 and 40 is 25.
Reason: Mean \(=\frac{10+20+30+40}{4}=\frac{100}{4}=25.\)
