Ranika wanted her friend Radhika’s mobile number. But Radhika played a trick. She gave her the number as
9 X Y Z P 1 Q 2 R 3
and told her to decode it with the help of following equations :
(a) `(3X-8)/(2X)=1`
(b) `(6Y-7)/(3Y+9)=1/3`
(c ) `(Z^(2)-9)/(5+Z^(2))=(-5)/9`
(d) `P+3/10P=13/10`
(e) `4( Q+4)=5(Q+2)`
(f) `3(R+10) + 200 = 236`
