Question

if 4 is subtracted from a number and it is divided divided by 8 then answer is 5. if 6 is added to that number and then it is divided by 10 then what is the answer? A) 5 B) 2 C) 6 D) 10​

Answer 1

Answer:

x-4/8=x+6/10

8x+48=10x-40

88x=2

x=44

fraction

x+6/10

44+6/10

50/10

=5

Answer 2

Given,

• If 4 is subtracted from a number and it is divided by 8 then answer is 5.
• If 6 is added to that number and it is divided by 10 .

To Find,

• When 6 is added to that number and it is divided by 10 then what will be the answer .

Solution :

★ $\sf{Suppose \ that \ number \ be \ "a "}$

$\mapsto \underline{\sf{\pink{According \ to \ the \ First \ Condition :}}}$

• If 4 is subtracted from a number and it is divided by 8 then answer is 5.

$\implies \sf{\dfrac{a - 4}{8}} = 5$

$\implies \sf{a - 4 = 5 \times 8}$

$\implies \sf{a - 4 = 40}$

$\implies \sf{a = 40 + 4}$

$\implies \underline{\boxed{\sf{a = 44}}}$

Now We have that Number So , We can easily find the finding number :-

$\mapsto \underline{\sf{\pink{According \ to \ the \ Second \ Condition :}}}$

• If 6 is added to that number and it is divided by 10 .

$\implies \sf{\dfrac{a - 6 }{10}}= \ ?$

$\implies \sf{\dfrac{44 + 6}{10} = \dfrac{50}{10} = \boxed{\sf{\pink{5}}}}$

Therefore,

$\boxed{\large{\bold{Option - A) \ 5}}}$
