The sum of the weight of 4 persons = 46 × 4 = 184 kg Let the weight of the lightest person = ‘x’ kg The weight of the heaviest person = (x + 28) kg The sum of the weight of the remaining two persons = 47 × 2 = 94 kg According to the question, x + x + 28 + 94 = 184 2x = 62 x = 31 The weight of the heaviest person = 31 + 28 = 59 kg

...If in two linear equations ax + by = c and dx + ey = f and a/d = b/e = c/f then, which of the following is true about the two equations?
The ratio of roots of an equation
ax²+bx+b = 0 is p : q
Then find, √p/√q + √q/√p + √p/√q ?
I. 2p2 + 5p + 2 = 0 II. 2q2 + 11 q + 14 = 0
I. p² - 365 = 364
II. q - √ 529 = √ 169
