Show answer & explanation
Correct answer: D. Statement (I) is false but Statement (II) is trueकथन (I) असत्य है, लेकिन कथन (II) सत्य है
Explanation
Statement (I): the extra profit of ₹160 equals (15% − 10%) = 5% of the cost price, so CP = 160 × 100/5 = ₹3,200, not ₹4,200 — false. Statement (II): take earnings 100 → expenses 80, savings 20. New earnings = 125, new expenses = 80 × 1.20 = 96, new savings = 29. Increase = 9/20 = 45% — true. Hence Statement (I) is false but Statement (II) is true.कथन (I): ₹160 का अतिरिक्त लाभ क्रय मूल्य के (15% − 10%) = 5% के बराबर है, अतः क्रय मूल्य = 160 × 100/5 = ₹3,200, न कि ₹4,200 — असत्य। कथन (II): आय 100 मानें → खर्च 80, बचत 20। नई आय = 125, नया खर्च = 80 × 1.20 = 96, नई बचत = 29। वृद्धि = 9/20 = 45% — सत्य। अतः कथन (I) असत्य, कथन (II) सत्य।More Mathematical Reasoning and Aptitude questions
