DIRECTIONS :( 1 – 4)In each of the following questions, if the given interchanges are made in signs and numbers, which of the four equations would be correct?
1. Given interchanges: Signs – and ÷ and number 4 and 8.
(a) 6 -8 ÷ 4 = -1 (b) 8 – 6 ÷ 4 = 1
(c) 4 ÷ 8 – 2 = 6 (d) 4 – 8 ÷ 6 = 2
2. Given interchanges: Signs + and x and numbers 4 and 5.
(a) 5 x 4 + 20 = 40 (b) 5 X 4 + 20 = 85
(c) 5 x 4 + 20 = 104 (d) 5 x 4 + 20 = 95
3. Given interchanges: Signs + and – and numbers 4 and 8.
(a) 4 ÷ 8 – 12 = 16 (b) 4 – 8 12 = 0
(c) 8 ÷ 4 – 12 = 24 (d)8 -4 ÷ 12 = 8
4. Given interchanges: Signs – and x and numbers 3 and 6.
(a) 6- 3 x 2 = 9 (b) 3 – 6 x 8 = 10
Directions (5 - 10): In each of the following questions, the two expressions on either side of the sign (=) will have the same value if two terms on either side or on the same side are interchanged. The correct terms to be interchanged have been given as one of the four alternatives under the expressions. Find the correct alternatives in each case.
5. 5 + 3 x 6 – 4 ÷ 2 = 4 x 3 – 10 ÷ 2 + 7
(a) 4,7 (b) 5,7
(c)6, 4 (d) 6 , 10
6. 7 x 3 – 3 + 5 ÷ 4 = 5 + 6 x 2 – 24 ÷ 3
(a) 2, 6 (b)6 ,5
(c) 3, 24 (d) 7,6
7. 15 + 3 x 4 -8 ÷ 2 = 8 x 5 + 16 ÷ 2 – 1
(a) 3, 5 (b) 15,5
(c) 15, 16 (d) 3,1
8. 6 x 3 + 8 ÷ 2 – 1 = 9 – 8 ÷ 4 + 5 x 2
(a) 3,4 (b) 3,5
(c) 6, 9 (d) 9,5
9. 8 ÷ 2 x 5 - 11 + 9 = 6 x 2 – 5 + 4 ÷ 2
(a) 5,9 (b) 8,5
(c)9,6 (d) 11, 5
10. Select the correct set of symbols which will fit in the given equation 5 0 3 5 = 20.
