RBSE Solutions for Class 7 Maths Chapter 6 वैदिक गणित Ex 6.2 Q1
हल:
(i) दाहिने से प्रारम्भ करते हुए बायीं ओर गणना करें। बायीं ओर के प्रत्येक शून्य के बदले 9 लिखें(RBSESolutions.com)और अन्तिम शून्य की जगह 10 लिखें। शून्य के पहले एक दम बायीं ओर का अंक कम हो जायेगा।

RBSE Solutions

(ii) (a) यहाँ 2 < 7
∴ 7 – 2 = 5 का पूरक लेते हैं।
5 का पूरक 5 है। जो इकाई के स्थान पर रखा जायेगा।
(b) 7< 8 अत: 8 – 7 = 1 पूरक 9 से 1 घटाने पर 8 आयेगा।
RBSE Solutions for Class 7 Maths Chapter 6 वैदिक गणित Ex 6.2 Q1b
(c) 8 < 9 अतः 9 – 8 = 1
पूरक 9 से 1 घटाने पर 8 आयेगा।
(d) 5 से एक कम 5 -1 = 4 में से 2 घटाने(RBSESolutions.com)पर 2 शेष आयेगा।

RBSE Solutions

(iii) (a) यहाँ 7 < 8
∴ 8 – 7 = 1 का पूरक लेते हैं।
∴ इकाई के स्थान पर 10 – 1 = 9
(b) 8 < 9 अंत: 9 – 8= 1, पूरक 9 में से 1 घटाने पर 8 आयेगी!
RBSE Solutions for Class 7 Maths Chapter 6 वैदिक गणित Ex 6.2 Q1c
(c) 9 > 8 अत: 9 – 8 = 1 पूरक 9 में से 9 घटाने पर 0 आयेगा।
(d) 4 – 1 = 3

प्रश्न 2
उपयुक्त सूत्र लगाकर गुणा कीजिए
(i) 87 x 10
(ii) 53 x 100
(iii) 432 x 1000
(iv) 64 x 5
(v) 72 x 50
(vi) 81 x 99
(vii) 99 x 999
(viii) 99 x 9
हल:
(i) 87 x 10 = 870
(ii) 53 x 100 = 5300
(iii) 432 x 1000 = 432000
(iv) 64 x 5 = 64 x \(\frac { 10 }{ 2 }\) = \(\frac { 64 }{ 2 }\) x 10
= 32 x 10 = 320
(v) 72 x 50 = 72 x \(\frac { 100 }{ 2 }\) = \(\frac { 72 }{ 2 }\) x 100
= 36 x 100 = 3600
(vi) 81 x 99 =
