Correct Answer: ? 900
Explanation:
Let the amount be ? a
According to the question,
a x 5/12= 33/4 x 100
? 5a/12 = 15/4 x 100
? a = 12/5 x 15/4 x 100
? a = 12 x 15 x 100/4 x 5
? a = ? 900
Correct Answer: ab > 0
Explanation:
If the fraction a/b is positive,
then a > 0 ..............(i)
and b > 0 ..............(ii)
Multiply (i) and (ii)
So ab > 0 must be true.
Correct Answer: data inadequate

Let number of boys in school are B and Girls are G.
Total number of students participated
= (B x 1/4 + G x 3/8)

Correct Answer: 3 %
Explanation:
Exp. = (.35 x .0015) / (.25 x .07)
= ( 35 x 15) / (25 x 7 x 100)
= (3/100) x 100 %
= 3%
Correct Answer: 0.024

= 3 /125
= 0.024
Correct Answer: 170 / 11

?4096/100+ ?4096/10000 + ?4096/1000000 + ?4096/100000000
=?4096 / 10 + ?4096/ 100 + ?4096/ 1000 + ?4096/ 10000
=64/10 + 64/100 + 64/1000 + 64/10000
=6.4 + .64 + .064 + .0064
