Answer : 3. "-40 degreees"
Explanation :

Answer: C) -40 degreees Explanation: We want the temperature when F=C. We know that, F = C x 95 + 32 So substituting C For F, we have C = -40o Therefore,  C = -40.  Thus when C = -40, we have C = F

Answer : 4. "1000(p - q) + qr"
Explanation :

Answer: D) 1000(p - q) + qr Explanation: We need to find the total cost to send r messsages, r > 1000. The first 1000 messsages will cost Rs.p each (Or)  The total cost of first 1000 messsages = Rs.1000p The remaining (r - 1000) messsages will cost Rs.q each (Or) The cost of the (r - 1000) = Rs.(r - 1000)y   Therefore, total cost = 1000p + rq - 1000q = 1000(p - q) + qr

Answer : 3. "4349 days"
Explanation :

Answer: C) Option C Explanation: Raghu can complete the work in (12 x 9)hrs = 108 hrs.    Arun can complete the work in (8 x 11)hrs = 88 hrs.   Raghu's 1 hrs work = 1/108 and Arun's 1 hrs work = 1/88   (Raghu + Arun)'s 1 hrs work = 1108+188=492376  So, both Raghu and Arun will finish the work in 237649 hrs Number of days of 12 hours each=237649×112 = 19849=4349 days
