A2 : 3

B1 : 3

C3 : 2

D3 :1

Answer:

D. 3 :1

Read Explanation:

കി.ഗ്രാമിന് 50 രൂപ വിലയുള്ള വെളിച്ചെണ്ണയുടെ അളവ് = x

കി.ഗ്രാമിന് 70 രൂപ വിലയുള്ള വെളിച്ചെണ്ണയുടെ അളവ് = y

ആകെ ചിലവായ തുക

50x+70y=55(x+y)50 x + 70 y = 55 (x+y)

50x+70y=55x+55y50 x + 70 y = 55 x + 55 y

15y=5x15 y = 5 x

xy=155\frac{x}{y} =\frac{15}{5}

=31= \frac{3}{1}

അംശബന്ധം x:y=3:1x:y= 3 : 1
