Question 4 |
If P = [(7/9 – 37/9) / 41/5] + [{1/2(31/2)} / (59/3 – 85/9)] then what will be the value of P
-1403/121 | |
-3121/140 | |
0 | |
none |
Question 4 Explanation:
Just solve the question using the BODMAS rule and you will get B as the correct answer.
Question 5 |
If P = [{1/2/ (¼ -1/2 -1/2)}] x [(4/5)/(21/2 + 31/2)] - 21 then what we can say for P
P will be a proper fraction | |
P will be a Improper fraction | |
P will be a negative improper fraction | |
None |
Question 5 Explanation:
[{1/2/ (¼ -1/2 -1/2)}] = (½)/(-3/4)= -2/3
[(4/5)/(21/2 + 31/2)]
= (4/5)/(5/7 +7/2)
= (4/5) / 6 =2/15
So -2/3 x 2/15 = -4/45
And -4/45 -21 = -949/45
So the best answer to this problem is Option C
[(4/5)/(21/2 + 31/2)]
= (4/5)/(5/7 +7/2)
= (4/5) / 6 =2/15
So -2/3 x 2/15 = -4/45
And -4/45 -21 = -949/45
So the best answer to this problem is Option C
