Answer Key-
Q-(1) Sol-(1)
Q-(2) Sol-(5)
1st day he read = 40%
2nd day he read =34 %
remaining = 100% - (40% +34%) = 26%
Last day he read =13%
13% = 52
1% = 4
100% = 400
Total page is 400.
Q-(3) Sol-(4)
Ratio of boys and girls = 100% : 75% = 4:3
Difference is 1 unit=30
So, 3 units = 90
If 20% absent, that’s mean 80% present.
So, present girls = 80% of 90 = 72
Q-(4) Sol-(3)
Q-(5) Sol-(2)
Together can do 5 units.
In 8 days they can do = 5 x 8 =40 unit
Remaining is = 60 – 40 = 20 unit
If they work alternately
1st day B will do 2 units.
2nd day A will do 3 units.
2 days they will do 5 units.
To complete 20 units, it will take = 8
Total days = 8 +8 =16 days
Q-(6) Sol-(1)
(x+6)2 = 0 or x = -6,
(y+8)2 = 0 or y = -8
Hence x > y
Q-(7) Sol-(1)
x = -7, 15 y = -8, -11
Hence x > y
Q-(8) Sol-(3)
x = 4.5, -4.5 y = 5.5
Hence x < y
Q-(9) Sol-(1)
Q-(10) Sol-(4)
x = 2, 5
y = 5, 7
Hence x < y
