Question:

If x : y = 3 : 4, then (7x + 2y) : (7x − 2y) is equal to?

यदि x : y = 3 : 4 है, तो (7x + 2y) : (7x − 2y) किसके बराबर है?

Options:

  • a) 20 : 11
  • b) 21 : 12
  • c) 25 : 13
  • d) 29 : 13
  • a) 20 : 11
  • b) 21 : 12
  • c) 25 : 13
  • d) 29 : 13

correct answer : d)

Explanation:

Put x = 3, y = 4. Numerator: 7(3) + 2(4) = 21 + 8 = 29. Denominator: 7(3) – 2(4) = 21 – 8 = 13. Ratio is 29:13.

x = 3, y = 4 रखने पर। अंश: 7(3) + 2(4) = 21 + 8 = 29. हर: 7(3) – 2(4) = 21 – 8 = 13. अनुपात 29:13 है।
