50 ലിറ്റർ ക്യാനിൽ; പാലും വെള്ളവും 3: 1 എന്ന അനുപാതത്തിലാണ്. അനുപാതം 1: 3 ആയിരിക്കണമെങ്കിൽ, എത്രത്തോളം കൂടുതൽ വെള്ളം ചേർക്കണം?

A120 ലിറ്റർ

B100 ലിറ്റർ

C80 ലിറ്റർ

D90 ലിറ്റർ

Answer:

B. 100 ലിറ്റർ

Read Explanation:

ക്യാനിലെ പാലിന്റെ അളവ് = 50 × (3/4) = 150/4 = 37.5 ലിറ്റർ ക്യാനിലെ ജലത്തിന്റെ അളവ് = 50 - 37.5 = 12.5 ലിറ്റർ കൂടുതൽ വെള്ളം ചേർക്കുമ്പോൾ ലഭിക്കേണ്ട അനുപാതം = 1: 3 37.5 / (12.5 + x) = 1/3 112.5 = 12.5 + x 112.5 - 12.5 = x x = 100
