If A:B= 2:3,B:C = 4:5 and C : D=5 :9, then A: D is equal to- यदि A:B= 2:3,B:C = 4:5 और C : D=5 :9 हो, तो A: D बराबर होगा?

If A=2 div 3xx4 , B=3 of 4 +(7-2) and C=4+5-6 , then what is the value of A+B+C? यदि A=2 div 3xx4 , B=3 of 4 +(7-2) और C=4+5-6 है, तो A+B+C का मान क्या होगा ?

If A={1,2,3,4,5} and B={1,3,5,7,9} then find the value of (A-B)uu(B-A)
