​

Answer 1

Step-by-step explanation:

40 prekshan ka ausat == 50

isliye 40 prekshano ka yog == 40*50= 2000

60 prekshan ka ausat == 55

isliye in 60 prekshano ka yog == 60*55= 3300

ab, sabhi prekshano ki kul sankhya == 40+60=100

isliye, in 100 prekshano ka ausat == 100 prekshan ka yog / kul sankhya

== (40 prekshan ka yog + 60 prekshan ka yog) /100

(2000+3300)/100== 5300/100 == 53.

isliye in sabhi prekshano ka ausat 53 hoga.
