45÷9
8×5
9+8
8×5−45
SOLUTION
Solution : A
BODMAS = B - Brackets
O - Of
D - Division
M - Multiplication
A - Addition
S - Subtraction
The given expression is 45÷9+8×5−45
According to BODMAS, Division is done before Multiplication, Addition and Subtraction.
Hence, "45÷9" is the operation that needs to be performed first.
Question 2
Which is greater: 50 tens 5 ones or 4 hundreds, 9 tens and 9 ones?
50 Tens 5 ones
4 hundreds 9 Tens 9 ones
Both are equal
5 Tens 50 ones
SOLUTION
Solution : A
50 Tens 5 Ones = 50×10+5×1=500+5=505
4 Hundreds, 9 Tens 9 Ones = 4×100+9×10+9×1=400+90+9=499
505>499
Hence, 50 Tens 5 Ones is greater.

Question 4
By how much, is 15×7 greater than 15+7?
80
105
22
83
SOLUTION
Solution : D
15×7=105
15+7=22
105−22––––– 83
105 is 83 more than 22.
Question 5
What is the number obtained when two lakhs two hundred is subtracted from 2,22,222 and then divided by 2?
11011
10011
10101
11100
SOLUTION
Solution : A
Two lakhs two hundred = 2,00,200
When 2,00,200 is subtracted from 2,22,222, we have:
2,22,222− 2,00,200––––––––––––– 22022––––––––––––
When 22022 is divided by 2, we get:
220222=11011
Question 6
55555÷5−1111=?
10 hundreds
100 thousands
1 thousand
10 thousands
SOLUTION
Solution : D
55555÷5
= 555555
= 11111
Now,
= 11111 − 1111 –––––––– 10,000 ––––––––=10 thousands
Question 7
What number is obtained when 4040404 is doubled and then divided by 2?
4004404
4040404
4000404
4400444
SOLUTION
Solution : B
4040404 doubled means multiplied by 2.
4040404× 2 ––––––––– 8080808 –––––––––––
8080808, when divided by 2, means it is halved.
→ 8080808÷2
= 80808082
=4040404
Question 8
How many packets of chips, each weighing 250 g can be made from a 5000 g pack?
25
10
50
20
SOLUTION
Solution : D
Weight of each pack of chips = 250 g
Total weight of the big pack = 5000 g
No of packets of chips with 250 g of chips
= 5000÷250
= 5000250
= 20 packs
Question 9
A and B travel from home to school and back once a day. How much more distance does B travel from Monday to Friday?
20 km
10 km
2 km
1 km
SOLUTION
Solution : B
Monday to Friday = 5 days
Distance travelled by A in 1 day
Distance travelled by B in 1 day
Total distance travelled by A in 5 days
= 2×5=10 kmTotal distance travelled by B in 5 days
= 4×5=20 kmSo, B travels (20−10) km = 10 km more than A from Monday to Friday.
Question 10
Class 5 had 43 children & Class 6 had 29 children. For a field trip, equal number of children were put into 4 buses. How many children were put in each bus?
20
72
18
16
SOLUTION
Solution : C
Number of children in class 5 = 43
Number of children in class 6 = 29
Total number of children = 43+29=72
Number of buses = 4
Number of children in each bus
= 72÷4
18 472 −4–2 32 − 32––– 0Therefore, number of children in each bus is 18.
