यदि 25% of 240 + 15 × 4 - 36 ÷ 6 का मान ज्ञात कीजिए।
[A]
84
[B]
90
[C]
96
[D]
100
1.
[A]
[B]
[C]
[D]
सही उत्तर:
90
व्याख्या:
25% of 240 = 60, 15 × 4 = 60 तथा 36 ÷ 6 = 6। अतः 60 + 60 - 6 = 114। इसलिए सही उत्तर 114 होगा।
Correct Answer:
Explanation:
This is an important Simplification question.

2.
What is the value of 441 ÷ [270 ÷ (3/7 of 35) + (17 ÷ 1/3) - (8 1/2 - 5/2)]?
[A]
7
[B]
21
[C]
11
[D]
14
सही उत्तर:
7
व्याख्या:
BODMAS के अनुसार पहले 3/7 का 35 = 15, 17 ÷ 1/3 = 51 तथा 8 1/2 - 5/2 = 6। अतः 441 ÷ [270 ÷ 15 + 51 - 6] = 441 ÷ 63 = 7।
Correct Answer:
7
Explanation:
Using BODMAS, 3/7 of 35 = 15, 17 ÷ 1/3 = 51 and 8 1/2 - 5/2 = 6. Therefore, 441 ÷ [270 ÷ 15 + 51 - 6] = 441 ÷ 63 = 7.
3.
480 का 25% + 500 का 30% + 90 का x% = 900 का 35% है, तो x का मान क्या है?
[A]
45
[B]
50
[C]
55
[D]
40
3.
If 25% of 480 + 30% of 500 + x% of 90 = 35% of 900, then find x.
[A]
45
[B]
50
[C]
55
[D]
40
सही उत्तर:
50
व्याख्या:
480 का 25% = 120, 500 का 30% = 150 और 900 का 35% = 315। अतः 120 + 150 + 0.9x = 315, इसलिए 0.9x = 45 और x = 50।
Correct Answer:
50
Explanation:
25% of 480 = 120, 30% of 500 = 150 and 35% of 900 = 315. Therefore, 120 + 150 + 0.9x = 315, giving x = 50.

Correct Answer:
66
Explanation:
18 ÷ 3 = 6 and then 6 × 2 = 12. Therefore, 72 - 12 + 6 = 66.
