Question

How much flour does she use in all during the day? / एक रसोइया सुबह रोटी के लिए 3/4 किलोग्राम आटा और दोपहर केक के लिए 2/3 किलोग्राम आटा प्रयोग करती है। दिन भर में वह कुल कितना आटा प्रयोग करती है?
Option 4 : 17/12
Detailed Solution
सही उत्तर 17/12 है।
3/4 + 2/3 = 9/12 + 8/12 = 17/12 kg. Note the trap: adding numerators and denominators directly would wrongly give 5/7. / 3/4 + 2/3 = 9/12 + 8/12 = 17/12 किलोग्राम। ध्यान दें: अंशों और हरों को सीधे जोड़ने पर गलत 5/7 मिलेगा।
