If p is directly proportional to q and p = 7 when q = 6, then what is the value of p when q = 21?
यदि p, q के अनुक्रमानुपाती है और q = 6 होने पर p = 7 है, तो q = 21 होने पर p का मान ज्ञात कीजिए।
Answer और ExplanationAnswer and explanation
Answer: (B) 24.5
pq = स्थिर
76 = p21
p = 7 × 216 = 24.5
✓
p = 24.5
pq = constant
76 = p21
p = 7 × 216 = 24.5
✓
p = 24.5
SMART APPROACH
q, 216 = 3.5 गुना हुआ, तो p = 7 × 3.5 = 24.5।
q becomes 216 = 3.5 times, so p = 7 × 3.5 = 24.5.
