Directions(1-10) : 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..
1. 6 x 3 + 8 ÷ 2 – 1 = 9 – 8 ÷ 4 + 5 x 2
(a) 3,4 (b) 3,5
(c) 6, 9 (d) 9,5
2. 8 ÷ 2 x 5 - 11 + 9 = 6 x 2 – 5 + 4 ÷ 2
(a) 5,9 (b) 8,5
(c)9,6 (d) 11, 5
3. 15 + 3 x 4 -8 ÷ 2 = 8 x 5 + 16 ÷ 2 – 1
(a) 3, 5 (b) 15,5
(c) 15, 16 (d) 3,1
4. Select the correct set of symbols which will fit in the given equation 5 0 3 5 = 20.
(a) x,x,x (b) -,+,x
(c) x, +,x (d) +,-,+
5. If A + B > C + D and B + C > A + D, then it is definite that
(a) D > B (b) C > D
(c)A > D (d) B > D
6. If A > B, B > C and C> D, then which of the following conclusions is definitely wrong?
(a) A > D (b) A > C
(c) D > A (d) B> D
7. If A + B = 2C and C + D = 2A,then
(a) A + C = B + D (b) A + C = 2D
(c) A + D = B + C (d) A + C = 2B
8. If A + B = C + D and A + D > B + C, then which one of the following is definitely wrong?
(a) A > B (b) A>C
(c) C >D (d) B > D
9. If ‘+’ stands for ‘division’, ‘÷’ stands for ‘multiplication’, ‘x’ stands for ‘subtraction’ and ‘-‘stands for ‘addition’, which one of the following is correct?
(a) 18 ÷ 6 x 7 + 5 – 2 = 22 (b) 18 x 6 + 7 ÷ 5 -2 = 11
(c) 18 ÷ 6 -7 +5 x 2 = 20 (d) 18 + 6 ÷ 7 x 5 – 2 18
10. If A + D > C + E , C + D = 2B and B + E > C + D , it necessarily follows that
(a) B + D > C + E (b) A + B > 2D
(c) A + D > B + E (d) A + D > B + C
