Ques 1: See if you can do the same with these sums.
Ans:
Ques 1: Now work out the steps in your mind. Write the answers directily in the boxes.
33 + 42 =__
19 + 61 =__
__= 48 + 42
__= 33 + 27
__= 34 + 63
__= 53 + 64
55 + 25 =__
67 + 25 =__
72 + 56 =__
Ans:
33 + 42 = 75
19 + 61 = 80
90 = 48 + 42
60 = 33 + 27
97 = 34 + 63
117 = 53 + 64
55 + 25 = 80
67 + 25 = 92
72 + 56 = 128
2: A shopkeeper Rafi had 153 candles. Paras gave him 237 more candles. How many candles does Rafi have now?
Ans: Number of candles with Rafi = 153
Number of candles given by Paras to Rafi = 237
Total number of candles with Rafi = 237 + 153 = 390
Thus, Rafi has a total of 390 candles.
Work out the following story problems in the same way. Read each problem and say it in your words. Guess the answer before writing it.
A: A train compartment is carrying 132 people. Another compartment is carrying 129 people. In all, how many people are there in both the compartments?
Ans: Number of people in the first compartment = 132
Number of people in the second compartment = 129
Total number of people in both the compartments = 132 + 129 = 261
Thus, there are 261 people in both the compartments.
B: Shanu found 138 pebbles. Karim found 44 pebbles. How many pebbles did they find in all?
Ans:
Number of pebbles with Shanu = 138
Number of pebbles with Karim = 44
Total number of pebbles = 138 + 44 = 182
Thus, Shanu and Karim found 182 pebbles altogether.
C: A teacher kept a note of which fruits students like in her school. This is what she found:
Find out:
(a) How many students in the school like oranges?
(b) How many students in the school like mangoes?
(c) Altogether, how many students are there in the school?
(d) Is the number of girls more than 350 or less than 350?
Ans:
(a) Number of girls who like oranges = 136
Number of boys who like oranges = 128
Total number of students who like oranges = 136 + 128 = 264
(b) Number of girls who like mangoes = 240
Number of boys who like mangoes = 243
Total number of students who like mangoes = 240 + 243 = 483
(c) Total number of students in the school = 264 + 483 = 747
(d) Number of girls who like oranges = 136 Number of girls who like mangoes = 240 Total number of girls in the school = 136 + 240 = 376
Thus, the number of girls in the school is more than 350.
