Answer 2

Given: 8/5=40/25

To find The result after componendo-dividendo on 8/5=40/25

Solution: This componendo-dividendo is applicable for the fractional numbers, where numerator and denominator are there and we can execute this to perform and reduce the expressions. Consider an expression,

         x/y=p/q, then after applying componendo-dividendo, we have

(x+y)/(x-y)= (p+q)/(p-q)

Now from above, we have

8/5=40/25 [form:  x/y=p/q]

Applying componendo-dividendo on both sides, we get

(8+5)/(8-5) = (40+25)/(40-25)

⇒13/3 = 65/15

∴ The correct option is 4️⃣ 13/3=65/15​

Hence the result after componendo-dividendo on 8/5=40/25 is  4️⃣ 13/3=65/15​.
