Answers


S2. Ans.(a)
Sol. Required % = 10/(12+16)×100=1000/28=35.71% ≈36%

S3. Ans.(b)
Sol. Ratio = 19200×12∶25600×16
= 9 : 16

S4. Ans.(e)
Sol. Required Difference = (25600 × 18%) - (19200 × 20%) = 4608 - 3840 = 768




S5. Ans.(b)
Sol. Required % = (25600×21-19200×23)/(19200×23)×100=
(5376-4416)/4416×100=21.73 ≈22%

S6. Ans.(e)
Sol. Required Answer = 25600 × 16/100 = 4096

S7. Ans.(c)
Sol. x = -3, -5
y = 4, 8
So, x<y

S8. Ans.(c)
Sol. x = -5/2
Y = -3/2
So, x<y

S9. Ans.(e)
Sol. x = -5/6, -9/7
Y = -7/8, 3/4
relationship between x and y cannot be determined.

S10. Ans.(e)
Sol. x = 1/3, ¾
Y = -7/2, ¾
relationship between x and y cannot be determined.
