Question

1 80. If 12.5% of 1/3 rd of a number is 100, what is 1/2 of that number? (1) 2400 (2) 1200 (3) 800 (4) 1600 ​

Answer 1

Answer:

1/2 of that number is option (2) 1200

Step-by-step explanation:

Given : 12.5% of 1/3 rd of a number is 100

            1/2 of that number = ?

Solution : Let the number be a

∴ 12.5% of 1/3 rd of a number = a x 12.5/100 x 1/3 = 100

                                                    a = 100 x 100 x 3 /12.5

                                                       = 30000/12.5

                                                       = 2400

   The number a is 2400

∴ 1/2 of 2400 = 1/2 x 2400

                      = 1200
