Directions(1-5): What will be the approximate value of question mark ‘?’ in the following questions.
- 12% of 800 – 20% of 400 = 25% of ?
6055748264Option E
12% of 800 – 20% of 400 = 25% of ?
=>0.25*? = 0.12*800 – 0.20 *400
=>0.25*? = 96 – 80
=>0.25*? = 16
=>? = 64 - 8^3 + ? – 16^2 =7^3 + 11^2
196185208156174Option C
8^3 + ? – 16^2 =7^3 + 11^2
=>512 + ? – 256 = 343 + 121
=>256 + ? = 464
=>? = 208 - (9.98% of 599.98)/14.99 = ? – 11.98% of 299.99
4035255236Option A
(9.98% of 599.98)/14.99 = ? – 11.98% of 299.99
=>(10% of 600)/15 = ? – 12% of 300
=>(0.10*600)/15 = ? – 0.12*300
=>60/15 = ? – 36
=>? = 40 - 19.98% of 819.99 = 24.98% of ?
600656745700620Option B
19.98% of 819.99 = 24.98% of ?
=>20% of 820 = 25% of ?
=>0.25*? = 164
=>? = 656 - 280/14 * 15 + 25^2 = ?^2 + 20% of 125
2010302515Option C
280/14 * 15 + 25^2 = ?^2 + 20% of 125
=>?^2 + (1/5) *125 = 20*15 + 625
=>?^2 + 25 =300 + 625
=>?^2 = 300+ 625 – 25
=> ? = 30 - Find the average number of children who were not given Polio drops from villages A,C and D taken together.
2533204240Option D
Required average = (62+32+32)/3 = 42 - The number of children who were given Polio drops in village E is what percentage of number of children who were not given Polio drops in village E?
200%220%320%150%100%Option A
Required% = (216/108)*100 = 200% - Find the difference between the total number of children to whom Polio drops were given in village A and B taken together and total number of children of children in village E.
1820111612Option D
Required Difference = (192+148)- 324 = 16 - In village F, out of 320 children, only 75% were given Polio drops and the number of boys who were given Polio drops was 25% more than the number of children to whom Polio drops were given in village C. Find the number of girls who were given Polio drops in village F.
5277466885Option E
Number of children to whom Polio drops was given in village F = 0.75*320 = 240
Number of boys who were given Polio drops in village F = 1.25*124 = 155
Number of girls who were given Polio drops in village F = 240 – 155 = 85 - The ratio of boys and girls in village D is 5:3 resp. and ratio of boys and girls to whom Polio drops were not given in village D is 3:1 resp. Find the ratio of number of boys to the number of girls who were given Polio drops in village D.
71:4473:4772:4966:5370:41Option B
Number of boys in village D = 5/8*272 = 170
Number of boys to whom Polio drops was not given in village D = ¾*32 = 24
Number of boys to whom Polio drop was given in village D = 170 – 24 = 146
Number of girls to whom Polio drop was given in village D = 240 – 146 = 94
Required ratio = 146:94 = 73:47
