Direction (Q. 1 - 5): What should come in place of question mark (?) in each of the following questions?
47% of492 = ?
? = 47x492/100 = 231.24
1825 - ( 4 6 x 1.65)=?
1825/46.65 = 24.04
6/5 of 7/4 of 12184 = ?
6/5 x 7/4 x 12184 = 255864
67.80 + 4235 + 64.52 + ?= 5321.32
67.80 + 4235 + 64.52 + ? = 5321.32
4367.32 + ? = 5321.32
? = 5321.32 - 4367.32 = 954
12% of 140 + 20 = ?
12x140/100 + 20 = 16.8 + 20 = 36.8
28%of420 - ?%of320 = 80
28x420/100 - 80 = 320x?/100
117.6 - 80 = 320x?/100 Therefore, ? = 37.6x100/320 = 11.75
2.65 x 4.8 x 17.3 - 42.36 =?
2.65 x 4.8 x 17.3 - 42.36
= 220.056 - 42.36 = 177.696
67562 + 77320 =?+52314
67562 + 77320 = x + 52314
144882 - 52314 = x
x = 92568
203 x 53 -(600) = (?)2
20 x 20 x 20 x 5 x 5 x 5 - (6 x 6 x 100 x 100)
= 8000 x 125 - 36000
= 1000000 - 360000 = 640000
= (800)- Therefore, ? = 800
6.8 x?= 530. 2
? - 5302/6.8 = 77.970
