Question

Libra had three diamond weighing equal. One of the diamond fell and broke into 4 equal pieces weighing
20gm each. what was the total weight of three diamonds.
(a) 200 gm
(b) 280 gm
(c) 320 gm
(d) 240 gm

Answer 1

It's an impractical question because you know the hardness of diamond.
But anyway right answer is 240gm

Answer 2

Answer:

Step-by-step explanation:

Libra has total diamonds = 3

 it is given in the question that weight of each diamond is same

 now one diamond accidentally got broke and it broke such that it now divided into 4 equal parts

  weight of each part if given and that is : 20gm

therefore weight of 1 whole diamond : 4 * weight of each broken part

                                                                  : 4 * 20gm

                                                                   : 80gm

now we know weight of one diamond is 80gm  therefore we calculate the how much 3 complete diamonds will weight

                      = weight of 1 diamond * total diamonds present initially

                       = 80gms * 3

                        = 240 gm  Final ANS
