SSC Constable GD Paper : Elementary Mathematics

Solution :

Let the weight of ( A_3 ) be ( x ).

According to the problem:

  • The weight of ( A_2 ) is 50% more than ( A_3 ), so:
    A_2 = x + 0.5x = 1.5x
  • The weight of ( A_1 ) is six times the weight of ( A_2 ), so:

The average weight of ( A_1 ), ( A_2 ), and ( A_3 ) is given as 299 kg, so:

Substitute the values of ( A_1 ), ( A_2 ), and ( A_3 ):



Now, solve for ( x ):

Thus, the weight of ( A_3 ) is 78 kg.

Now, the weight of ( A_1 ) is:

So, the weight of ( A_1 ) is 702 kg.
