A question and two statements are given. Which statement(s) is/are necessary/sufficient to answer the question. Question: There are 10 bars of 2 different weights. What is their total weight? Statement: 1. Half the weight of one fifth of 10 bars is 2 kg. 2. Of the remaining bars, one-fourth of the bar's weight is 0.5 kg. Correct Answer Statements 1 and 2 together are not sufficient

Given:

There are 10 bars of 2 different weights

Statement: 1

10 × 1/5 = 2

Weight of 2 bars = 2 × 2 = 4 kg

So, the weight of 1st type bar is 2 kg

Statement: 2

8 × 1/4 = 2 

Weight of 2 bars = 0.5

Weight of 1 bar = 0.25 kg

So, the weight of 2nd type bar is 0.25 kg

But here we don't have any information about how many bars for type 1 and type 2

∴ Statements 1 and 2 together are not sufficient
