In a market, one pineapple weighs 500gm one Banana weighs 200gm. and an apple weighs 250gm. What is the weight of 12 Bananas? 

The correct answer is: 2400g

Step by step solution:
Given,
weight of one banana = 200 gm
Number of bananas whose weight is to be found = 12
Therefore, weight of 12 banana = 12 x 200 gm
= 2400 gm
Hence, option(c) 2400 g is the correct option.

Another approach to the question could be that we can simply add the weight of a single banana(i.e., 200 gm) 12 times since the weight of 12 bananas are required to find out.
Thus, weight of 12 bananas = 200gm + 200gm + 200gm + 200gm + 200gm + 200gm + 200gm +200gm + 200gm + 200gm + 200gm + 200gm = 2400 gm
Thus, option(d) is the correct option.
