10 play kabadi , 35 play kho kho only , 5 play both gmaes . then how many in total ?
"10 play kabadi = > n ( a ) = 10 , 5 play both gmaes . = > n ( anb ) = 5 35 play kho kho only , = > n ( b ) = n ( b only ) + n ( anb ) = 35 + 5 = 40 total = > n ( aub ) = n ( a ) + n ( b ) - n ( anb ) = 10 + 40 - 5 = 45 answer : e"
subtract(add(10, add(35, 5)), 5)
