D. 40%

View Answer	Favorite Question	Report

Answer: Option C

Explanation:

ধরি, x = 100; তাহলে,w= 100-100 এর 10%=100-10=90

আবার, z= 100 ; তাহলে, y= 100-100 এর 30%= 100-30=70

এখানে, wy= 90×70=6300

এবং, xz=100×100=10000

wy,xz এর চেয়ে শতকরা কম হবে= 10000-6300/10000 ×100

= 3700/10000 ×100= 37%

A. 3
B. -3
D. $\sqrt{3}$

View Answer	Favorite Question	Report

Answer: Option C

Explanation:

\sqrt{x + 3} = \sqrt{x} + \sqrt{3} \Rightarrow {(\sqrt{x + 3})}^{2} = {(\sqrt{x} + \sqrt{3})}^{2} [বর্গ করে] \Rightarrow x + 3 = {(\sqrt{x})}^{2} + 2 \sqrt{x} . \sqrt{3} + {(\sqrt{3})}^{2} \Rightarrow x + 3 - x - 3 = 2 \sqrt{x} . \sqrt{3} \Rightarrow 0^{2} = {(2 \sqrt{x} . \sqrt{3})}^{2} [বর্গ করে] \Rightarrow 0 = 4 . x . 3 \Rightarrow x = \frac{0}{12} \Rightarrow x = 0 Answer : 0

So, 2y=z

But in option D, x-y=2z

So, y-y = 2z or, z =0 which is not possible so option D is not true

A. 0.5
B. 4.5
C. 3.5
D. 4

View Answer	Favorite Question	Report

Answer: Option B

Explanation:

Here, x + y = 4

And, x - y = 3

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

So, 2x = 7 [by addition]

or, x = 7/2 = 3.5

So, 3.5 + y = 4 [from first equation]

or, y = 4 - 3.5 = 2.5

Then, x + 2y = 3.5 + 2×0.5 = 3.5 + 1 = 4.5
