(ii) `q xx q xx q`

EQUALITY OF RATIONAL NUMBERS Two rational numbers (p)/(q) and (r)/(s) are equal if p xx s=q xx r.

1245 is a factor of the numbers p and q. Which of the following will ALWAYS have 1245 as a factor? (i) p + q (ii) p xx q (iii) p -: q

((1) / (2) pq- (3) / (2) q) xx (pq-q)

(i) 'P div Q' means 'Q' is father of P'. (ii) 'P xx Q' means 'P is sister of Q'. (iii) 'P + Q' means 'P is brother of Q'. (iv) 'P - Q' means 'Q is mother of P'. Which of the following means R is nephew of T ?

These questions are based on the following information. (i) ' P xx Q ' means 'P is brother of Q'. (ii) 'P div Q' means 'Q is mother of P'. (iii) 'P - Q' means 'P is father of Q'. (iv) 'P + Q' means 'Q is sister of P'. Which of the following means D is the grandfather of W?

if 56 xx 75 xx 60 xx 84 xx 210 = 2^p xx 3^q xx 5^r xx 7^s , then what is the value of [(p+q)//s]+r = ?

State whether the statements given are True or False. If (p)/(q) is a rational number and m is a non-zero integer, then (p xx m)/( q xx m) is a rational number not equivalent to (p)/(q) .
