1.  In a regular week, there are 5 working days and for each day, the working hours are 8. A man gets Rs. 2.40 per hour for regular work and Rs. 3.20 per hours for overtime. If he earns Rs. 432 in 4 weeks, then how many hours does he work for ? 

Your Answer: Option (Not Answered) Correct Answer: Option B Explanation: Suppose the man works overtime for x hours. Now, working hours in 4 weeks = (5 x 8 x 4) = 160. 160 x 2.40 + x x 3.20 = 432 3.20x = 432  384 = 48 x = 15. Hence, total hours of work = (160 + 15) = 175.

Your Answer: Option (Not Answered) Correct Answer: Option C Explanation: Total age of 11 players = (28 x 11) years = 308 years. I. C = Y + 11 C  Y = 11 .... (i) II. Total age of 10 players (excluding captain) = (27.3 x 10) years = 273 years. Age of captain = (308  273) years = 35 years. Thus, C = 35. .... (ii) From (i) and (ii), we get Y = 24 III. Total age of 9 players = [ (25 x 3) + (28 x 3) + (30 x 3)] years = 249 years. C + Y = (308  249) = 59 .... (iii) From (i) and (iii), we get C = 35. Thus, II alone gives the answer. Also, I and III together give the answer. Correct answer is (C). Learn more problems on : Average Discuss about this problem : Discuss in Forum 
4.  In a twodigit, if it is known that its unit's digit exceeds its ten's digit by 2 and that the product of the given number and the sum of its digits is equal to 144, then the number is: 

Your Answer: Option (Not Answered) Correct Answer: Option A Explanation: Let the ten's digit be x. Then, unit's digit = x + 2. Number = 10x + (x + 2) = 11x + 2. Sum of digits = x + (x + 2) = 2x + 2. (11x + 2)(2x + 2) = 144 22x^{2} + 26x  140 = 0 11x^{2} + 13x  70 = 0 (x  2)(11x + 35) = 0 x = 2. Hence, required number = 11x + 2 = 24.

7. 


Your Answer: Option (Not Answered) Correct Answer: Option E Explanation: I. Let the present ages of Tanya and Rahul be 3x years and 4x years. II. After 5 years, (Tanya's age) : (Rahul's age) = 4 : 5. III. (Rahul's age) = (Tanya's age) + 5.
Tanya's age = 3x can be found. Thus, I and II give the answer. From I and III, we get 4x = 3x + 5. This gives x. Tanya's age = 3x can be found. Thus, I and III give the answer. From III : Let Tanya's present age be t years. Then Rahul's present age = (t + 5) years.
Thus, II and III give the answer. Correct answer is (E). Learn more problems on : Problems on Ages Discuss about this problem : Discuss in Forum
