कुछ समीकरण कुछ सिस्टम के आधार पर हल किए जाते हैं। उस आधार पर अनसुलझे समीकरण के  लिए सही उत्तर ज्ञात करे।
6 + 5 + 3 = 23
4 + 2 + 7 = 30
7 + 6 + 5 = ?

Detailed Solution for Test: Mathematical Operations (गणितीय संचालन) - 2 - Question 1

जिस प्रकार ,
6 + 5 + 3 = (6 × 3) + 5 = 18 + 5 = 23
ओर
4 + 2 + 7 = (4 × 7) + 2 = 28 + 2 = 30
उसी प्रकार ,
7 + 6 + 5 = (7 × 5) + 6 = 35 + 6 = 41

यदि 83 – 51 = 32 और 26 – 19 = 20, तब 47 – 18 = ?

Detailed Solution for Test: Mathematical Operations (गणितीय संचालन) - 2 - Question 2

जैसे, 8 + 3 = 11 और 5 + 1 = 6, 11 – 6 = 5 = 3 + 2 => (32)
और, 2 + 6 = 8 और 1 + 9 = 10, 10 – 8 = 2 = 2 + 0 =>  (20)
इसी प्रकार, 4 + 7 = 11 और 1 + 8 = 9, 11 – 9 = 2 = 2 + 0 =>  (20)

Save

यदि 4* 5 = 30 , 5 * 6 = 42 और 6* 7 = 56 तब 4* 7 = ?

Detailed Solution for Test: Mathematical Operations (गणितीय संचालन) - 2 - Question 3

यहाँ पैटर्न निम्न है: सफल संख्याओं को परिणाम प्राप्त करने के लिए गुणा किया जाता है
4 * 5 = 5 x 6 = 30
5 * 6 = 6 x 7 = 42
6 * 7 = 7 x 8 = 56
4 * 7 = 5 x 8 = 40

यदि 13 L 4 A 7 = 41 और 14 A 3 L 12 = 54 हो, तो 12 L 3 A 9 = ?
Detailed Solution for Test: Mathematical Operations (गणितीय संचालन) - 2 - Question 4

L= + और A= x रखने पर,
12 + 3 x 9 = 12 + 27 = 39

Test: Mathematical Operations (गणितीय संचालन) - 2 - Question 5
Save

यदि 'x' का अर्थ '—', '÷' का अर्थ '+', '+' का अर्थ '×', '—' का अर्थ '÷' है, तब 200 × (180 — 90) ÷ (12 + 6) का मान क्या होगा?
Detailed Solution for Test: Mathematical Operations (गणितीय संचालन) - 2 - Question 5

200 × (180 - 90) ÷ (12 + 6) =?
परिवर्तित करने के बाद हमें अभिव्यक्ति प्राप्त होती है:
200 - (180 ÷ 90) + 12 × 6 = ?
200 - 2 + 72 = 270

Test: Mathematical Operations (गणितीय संचालन) - 2 - Question 6
Save

यदि × का मतलब है ÷, - का मतलब है ×,  ÷ का मतलब है + और + का मतलब है – तब (15 - 3  ÷ 11) × 8 + 6 = ?
Detailed Solution for Test: Mathematical Operations (गणितीय संचालन) - 2 - Question 6

दी गयी सूचना के आधार पर, हमे प्राप्त होता है-
(15 × 3 + 11) ÷ 8 - 6 = (45 + 11)  ÷ 8 - 6 = 56 ÷ 8 - 6 = 7 - 6 = 1

Test: Mathematical Operations (गणितीय संचालन) - 2 - Question 7

यदि `+’ का मतलब `x’, `-‘ का मतलब `+’, `x’ का मतलब `÷’ और '÷' का मतलब `-‘,इस सूचना के आधार पर निम्नलिखित प्रश्नों के उत्तर दीजिये-
8 x 4 – 6 ÷ 3 + 1 = ?
Detailed Solution for Test: Mathematical Operations (गणितीय संचालन) - 2 - Question 7

8 ÷ 4 + 6 – 3 x 1 = 2 + 6 - 3 = 5

Test: Mathematical Operations (गणितीय संचालन) - 2 - Question 8

उन दो चिन्हों का पता लगाएँ जिन्हें आपस में बदलने पर निम्न समीकरण सही हो जाता है|
5 + 4 x 8 - 16 ÷ 4 =3
Detailed Solution for Test: Mathematical Operations (गणितीय संचालन) - 2 - Question 8

- और ÷ को आपस में बदलने पर, हमें समीकरण प्राप्त होती है
5 + 4 x 8 ÷ 16 - 4 = 3
या 5 + 4 x (2 ÷ 4) - 4 = 3
या  3 = 3, जो कि सत्य है|

Test: Mathematical Operations (गणितीय संचालन) - 2 - Question 9

यदि × का मतलब +, < का मतलब -, + का मतलब ÷, > का मतलब ×, – का मतलब =,  ÷ का मतलब >, और = का मतलब <, तब निम्नलिखित में से कौनसा सही है?
Detailed Solution for Test: Mathematical Operations (गणितीय संचालन) - 2 - Question 9

दी गई सूचना के अनुसार समीकरण होगा:
विकल्प A) से
18/2 < 12 + 8 × 2
= 9 < 12 + 16
= 9 < 28
विकल्प B) से
अतः समीकरण 1) सही है|
15 + 3 × 8 < 2 – 14
15/2 + 3 + 8 - 2 = 14
16.5 और 14 बराबर नहीं है|
विकल्प C) से
8 × 12 + 3 – 14 × 2
8 + 12/3 = 14 +2
12 = 16 ( संभव नहीं)
विकल्प D) से
18 × 12 + 6 > 4 ÷ 12 × 18
18 + 12/6 × 4 > 12 + 18
18 + 2 × 4 > 30
26 > 30( संभव नहीं)

यदि 13 × 12 = 651 और 41 × 23 = 448 तो 24 × 22 = ?
Detailed Solution for Test: Mathematical Operations (गणितीय संचालन) - 2 - Question 10

संख्या के अंक आपस में बदलने पर-
13 × 12 = 31 × 21 = 651
41 × 23 = 14 × 32 = 448 
24 × 22 = 42 × 22 = 924
