MATHEMATICS TRICKS AND QUICK :->


यदि A:B=X:Y तथा B:C=P:Q हो ,तो A:C=X*P:Y*Q

A:B:C=(X:Y)*P:Y*Q
          = X*P:Y*P:Y*Q


EXAMPLE:->
                          यदि a और b की आय का अनुपात २:३ तथा b और c की आय का अनुपात ४:५ है ,तो a और c                         की आय का अनुपात क्या होगा तथा a,b और c की आय का अनुपात क्या होगा   ?

HINT-->
              a:b=2:3
              b:c=4:5

         a:c=2*4/3*5
              =8/15
a:b:c=2*4:4*3:3*5
       =8:12:15
