mangoes to Raju then they have equal no of mangoes. Find the
angos each of them had​

Answer 1

Answer:

5 is added to 100 observations each.  

So =500=(5×100) is added.  

Then divided by 100. ie 5.  

So mean increases by 5 to become 55.

S.D will remain same because every observation increased by 5 and mean also increased by 5.  

( standard deviation is the squareroot of the difference of mean and each observation divided by the number of observations )

(55,10)

Answer 2

Answer:

Step-by-step explanation:

suvo's mangoes X rajus mangoes y so X + Y=80

if suvo gives 20 percent to raju then thier mangoes will be equal

so Raju's 40 contains 20/100 of suvo

so the answer is suvo had 50 mangoes and Raju had 30 mangoes
