Copy and complete this table. 100 % 30 2500 120 % 12 . 5 % 6 0 . 5 % 4

The given table is : 100 % 30 2500 120 % 12 . 5 % 6 0 . 5 % 4 We observe in the first column, 100 % = 30 ⇒ 1 % of 30 = 1 100 × 30 = 0 . 3 ⇒ 120 % of 30 = 120 × 0 . 3 = 36 12 . 5 % of 30 = 12 . 5 × 0 . 3 = 3 . 75 0 . 5 % of 30 = 0 . 5 × 0 . 3 = 0 . 15 In the second column, 100 % = 2500 ⇒ 1 % of 2500 = 1 1 00 × 25 00 = 25 ⇒ 120 % of 2500 = 120 × 25 = 3000 12 . 5 % of 2500 = 12 . 5 × 25 = 312 . 5 0 . 5 % of 2500 = 0 . 5 × 25 = 12 . 5 Fourth column: Let 100 % = x ⇒ 12 . 5 % ( x ) = 6 ⇒ 12 . 5 100 × x = 6 ⇒ x = 46 × 100 12 . 5 = 368 ⇒ 1 % ( 368 ) = 1 100 × 368 = 3 . 68 ⇒ 120 % ( 368 ) = 120 × 3 . 68 = 441 . 6 0 . 5 % ( 368 ) = 0 . 5 × 3 . 68 = 1 . 84 Similarly, in the third column, Let 100 % = x ⇒ 0 . 5 % ( x ) = 4 ⇒ 0 . 5 100 × x = 4 ⇒ x = 4 × 100 0 . 5 = 800 1 % ( 800 ) = 1 1 00 × 8 00 = 8 ⇒ 120 % ( $ 800 ) = 120 × 8 = 960 12 . 5 % ( 800 ) = 12 . 5 × 8 = 100 Putting all the values in the table, we get 100 % 30 2500 800 368 120 % 36 3000 960 441 . 6 12 . 5 % 3 . 75 312 . 5 100 6 0 . 5 % 0 . 15 12 . 5 4 1 . 84 Hence, this table is the required answer.
