Answer:

The percentage of increase in Vinay's scores is $14$%.

Step-by-step explanation:

Given : Marks in SA1 = $70$

          Marks in SA2 = $84$

To find : The percentage of increase in Vinay scores =?

Solution :

• It is given that Vinay scores marks in SA1 = $70$

                                              Marks in SA2 = $84$

• We have to find the percentage of increase in Vinay scores.
• To find the percentage of increase in Vinay scores, we ahve to find his percentage scores of SA1 and SA2.
• The difference between percentage scores of SA1 and SA2 will be percentage of increase in Vinay scores.

• So,

        Percentage in SA1 = $\frac{70}{100} *100$%

                                    = $70$%

        Percentage in SA2 = $\frac{84}{100} *100$%    

                                     = $84$%

• Now, the percentage of increase in Vinay scores

                               = Percentage in SA2 - Percentage in SA1

                               = $84-70$

                               = $14$%

• ∴ The percentage of increase in Vinay's scores is $14$%.
