If 2x% be the percentage error in specific resistance given by rho=(pir^(2)R)/(l) where r is the radius having value (0.2 om 0.01) cm, R is the resistance of (60 pm 3) ohm and l is the length of (150 pm 1.5) cm. Find x.

ABCD is a parallelogram. L is a point on BC which divides BC in the ratio 1:2 . AL intersects BD at P.M is a point on DC which divides DC in the ratio 1 : 2 and AM intersects BD in Q. PQ : DB is equal to
