R and S

A sum of Rs. 1300 is divided among P, Q, R and S such that (P^(prime)s s h a r e)/(Q^(prime)s s h a r e)=(Q^(prime)s s h a r e)/(R^(prime)s s h a r e)=(R^(prime)s s h a r e)/(S^(prime)s s h a r e)=2/3dot How much is Ps share? R s .140 b. R s .160 c. R s .240 d. R s .320

If R = (x^(2)+2)/(x-3) and S =(x-1)/x , then find (a) R + S (b) R - S (c) R.S (d) R/S

If R:S=3:1 and S:T=1:5, then R:S:T=______.

The r^(th),s^(th) and t^(th) terms of a certain G.P. are R,S and T respectively,prove that R^(s-t)*S^(t-r)*T^(r-s)=1

If s_(n)=sum_(r

Divide Rs. .671 among A, B and C such that if their shares be increased Rs.3, Rs. 7 and Rs. 9 respectively the remainder shall be in the ratio 1 :2 : 3. R s .110 , R s .220 , R s .336 b. R s 112 , R s .223 , R s .336 c. R s .105 , R s .223 , R s .330 d. none of these

In Figure, P Q R S and A B R S are parallelograms and X is any point on side B Rdot Show that : a r(^(gm)P Q R S)=a r(^(gm)A B R S) a r(A X S)=1/2a r( P Q R S)
