Question

If 0.139 + 0.75 + 2.105 - (1.001) x 1.1 = 2 - k then the value of k is
0.1071
0.1075
0.8925
0.982​

Answer 1

EXPLANATION.

0.139 + 0.75 + 2.105 - (1.001) x 1.1 = 2 - k.

As we know that,

To find the value of k,

⇒ 0.889 + 2.105 - (1.001) x 1.1 = 2 - k.

⇒ 2.994 - (1.001) x 1.1 = 2 - k.

⇒ 2.994 - (1.1011) = 2 - k.

⇒ 2.994 - 1.1011 = 2 - k.

⇒ 1.8929 = 2 - k.

⇒ 1.8929 - 2 = -k.

⇒ -0.1071 = -k.

⇒ k = 0.1071.

Hence,

Option [A] is correct answer.

Answer 2

$\rm{0.139+0.75+2.105-\left(1.001\right)\cdot \:1.1=2-k}$

$\to\rm{0.139+0.75+2.105-1.001\cdot \:1.1+k=2-k+k}$

$\to\rm{2.994-1.001\cdot \:1.1+k=2}$

$\to\rm{2.994-1.1011+k=2}$

$\to\rm{1.8929+k=2}$

$\to\rm{k+1.8929-1.8929=2-1.8929}$

$\to\rm{k=0.1071}$
