14. In Fig. 9.28, AP || BQ II CR. Prove that
ar (AQC) = ar (PBR).
. Diagonals AC and BD of a quadrilateral
ABCD intersect at 0 in such a way that
ar (AOD) = ar (BOC). Prove that ABCD is a

71 - x = 8n
71 - x is the multiple of 8
if x = 1, 71 - x = 70 is not the multiple of 8,
The number which is nearest to 71 is 64 (multiple of 8).In order to make this 71 as 64, we have to subtract 7.
So, the value of x is 7.
Hence 7 is the least number.
(ii) 78 + x ≡ 3 (mod 5)
