Answer:
1. What are those two numbers whose sum is 58 and difference is 28?
Ans. The two numbers are whose sum is 58 and difference is 28 are 15 and 43.
2. The sum of two consecutive odd numbers is 56. Find the numbers.
Ans. (2x + 1) + (2x + 3) = 56. x = 13. Answers: The 2 numbers are: (2x + 1) = 26 + 1 = 27, and (2x + 3) = 26 + 3 = 29.
3. The sum of three consecutive multiples of 7 is 777. Find these multiples.
Ans. (7x + 7 + 7) will be the next number that is multiple of 7 after (7x + 7). Now according to the question, the sum of these three numbers is equal to 777. Hence, three consecutive multiples of 7 whose sum is equal to 777 are 252, 259 and 266.
4. A man walks 10 km, then travels a certain distance by train and then by bus as far as twice by the train. If the whole journey is of 70km, how far did he travel by train?
Ans. Let distance travelled by train be 'x'
According to the question,
10+x+2x= 70 km
3x + 10=70 km
3x= 70-10=60km
x=60/3=20 km
Distance travelled by train= 20km
Distance travelled by bus=20*2= 40 km
5. Vinay bought a cake and cut it into three pieces. When he weighed the first piece he found that it was 7g lighter than the second piece and 4g heavier than the third piece. If whole cake weighed 300g. How much did each of the three pieces weigh?
Ans. Weight of third piece to be considered " x "
Then, The Weight of First one Cake piece = x +4
Then second cake piece = first piece + Weight less /more
= (x +4)+ 7
= x + 11
Given Total weight = 300 g
x + x + 4 + x + 11 = 300
3x = 300-15
x = 285/3
x = 95
Therefore, Weight of
1) 1st Piece = x +4 = 95 +4 = 99
2) 2nd Piece = x + 11 = 95 +11 = 106
3) 3rd piece = x = 95
Total answer: The weight of the three pieces of pizza are 99g, 106g and 95g.
