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.

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

4004404

4040404

4000404

4400444

#### SOLUTION

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.
