1.	8. Which of the following expression are equal to-20 ?I 4x5II -32 + 10 -(-2)III 6x2-[-2 x 4]IV 5 (-2) + (-3) 4(a) I only(b) I and II(C) I, II and III (d) I, II, III and IV
Answer» the correct answer was (c) I - 4 * 5 = - 20II - 32 + 10 + 2 = - 20III - 62 - (-2-4) = - 12 - 8 = - 20IV 5-2 + (-3)4 = - 10 - 12 = - 22 Therefore,I, II and III are equal to - 20 (c) is correct option -4*-5 is the answer of this question (c)is correct answer

8. Which of the following expression are equal to-20 ?I 4x5II -32 + 10 -(-2)III 6x2-[-2 x 4]IV 5 (-2) + (-3) 4(a) I only(b) I and II(C) I, II and III (d) I, II, III and IV

Answer»

the correct answer was (c)

I - 4 * 5 = - 20II - 32 + 10 + 2 = - 20III - 6*2 - (-2*-4) = - 12 - 8 = - 20IV 5*-2 + (-3)*4 = - 10 - 12 = - 22

Therefore,I, II and III are equal to - 20

-4*-5 is the answer of this question

(c)is correct answer
