यदि (P(t)=40+4t) और (Q(t)=100-6t), तो किस (t) पर (P(t)) पहली बार (Q(t)) के बराबर होगा?
If (P(t)=40+4t) and (Q(t)=100-6t), at what (t) will (P(t)) first equal (Q(t))?
Explanation opens after your attempt
C. (t=6)
Concept
From (40+4t=100-6t), (10t=60). Therefore (t=6) is correct.
Why this answer is correct
The correct answer is C. (t=6). From (40+4t=100-6t), (10t=60). Therefore (t=6) is correct.
Exam Tip
(40+4t=100-6t) से (10t=60) होता है। इसलिए (t=6) सही है।
