Which of the following interchange of numbers and mathematical signs would make the given equation correct ? 28 ÷ 7 × 10 ÷ 5 - 20 = 5 |
10 and 20, × and + 5 and 20, - and ÷ 7 and 2, × and ÷ 5 and 10 , + and ÷ |
5 and 10 , + and ÷ |
Given equation; 28 + 07 x 10 ÷ 5 - 20 = 05 According to the que, after interchanging of numbers and mathematical signs; So, --> Option 01= 10 and 20, x and + 28 × 7 + 20 ÷ 5 - 10 = 5 28 × 7 + 4 - 10 = 5 196 + 4 - 10 = 5 200 - 10 = 5 190 \(\neq \)5 (LHS \(\neq \)RHS) --> Option 02= 5 and 20, - and + 28 + 7 × 10 - 20 ÷ 5 = 20 28 + 7 × 10 - 4 = 20 28 + 70 - 4 = 20 98 - 4 = 20 94 \(\neq \)20 (LHS \(\neq \)RHS) --> Option 03= 7 and 28, x and ÷ 7 + 28 ÷ 10 × 5 - 20 = 5 7+2.8x5-20=5 7 + 14 - 20 = 5 18 - 20 = 5 -2 \(\neq \)5 (LHS \(\neq \)RHS) --> Option 04= 5 and 10, + and ÷ 28 ÷ 7 × 5 + 10 - 20 = 10 4 × 5 + 10 - 20 = 10 20 + 10 - 20 = 10 30 - 20 = 10 10 = 10 (LHS = RHS) |
