Question

find the number which when increased by 6% becomes 1272 ​

Answer 1

Step-by-step explanation:

The carbon has 4 valence electrons and thus needs 4 more electrons from four hydrogen atoms to complete its octet. The hydrogen atoms are as far apart as possible at 109o bond angle. ... This creates an equal distribution to the atoms and gives it a tetrahedral geometry.

Answer 2

SOLUTION :

Let the number be x,
Then, According to the question,

6% of x + x = 1272
=> 6/100*x + x = 1272
=> 6x/100 + x = 1272
=> 106x/100 = 1272
=> 106x = 127200 (1272*100)
=> x = 127200/106
=> x = 1200 ( ANSWER )
