the LCM of 8,16 and 32 is 32 5/8=20/32 8/16=16/32 21/32=21/32 therefore, 16/32<20/32>21/32 also, 8/16<5/8>21/32 therefore 5/8 is between 8/16 and 21/32

5/8=10/16=20/32...so option B is out (19/32 is less than 20/32) Option C is out (10/16 is is greater than 8/16) and for same reason option D is also out So answer is option A

Given below are the steps of construction of a quadrilateral PQRS, where PQ = 5.5 cm, QR = 8.5 cm, ∠P = 75°,
∠Q = 105°, ∠R = 120°. Which of the following is a wrong step?
(i) Draw PQ = 5.5 cm.
(ii) Draw ∠XPQ = 75° at P and ∠PQY = 105° at Q.
(iii) With Q as centre and radius QR = 5.5 cm, draw an arc to intersect QY at R.
(iv) At R, draw ∠PSR = 120° such that RT meets PX at S.
PQRS is the required quadrilateral.

A(iii) only
B(ii) & (iv) only
C(iii) & (iv) only
D(iv) only


Confusing question. After step 3 is wrong, step 4 is wrong by definition
