Detailed Solution
Download Solution PDFदिलेले समीकरण:- 19 + 63 ÷ 7 – 8 × 12 = 79
दोन चिन्हे बदलून,
1) × आणि ÷
19 + 63 × 7 – 8 ÷ 12 = 79
19 + 441 – 0.67 = 79
460 – 0.67 = 79
459.33 = 79
2) – आणि ×
19 + 63 ÷ 7 × 8 - 12 = 79
19 + 9 × 8 – 12 = 79
19 + 72 – 12 = 79
91 – 12 = 79
79 = 79
येथे, पर्याय 2 सत्य आहे त्यामुळे उर्वरित पर्याय तपासण्याची गरज नाही.
अशा प्रकारे, योग्य उत्तर आहे “- आणि ×”.
