निम्नलिखित प्रश्न में प्रश्नवाचक चिह्न (?) के स्थान पर क्या आएगा:
√(1225) × 28 + 203 × 7 = ?²
(a) 47
(b) 45
(c) 49
(d) 51
(e) 53
Correct Answer: (c)
Explanation:
√(1225) = 35
35 × 28 = 980
203 × 7 = 1421
980 + 1421 = 2401 = 49².
So ? = 49.
√(1225) = 35
35 × 28 = 980
203 × 7 = 1421
980 + 1421 = 2401 = 49².
अतः ? = 49।
