= 108 + 152/21

= 260/21

= 12 8/21

(d) 3/10 of 91/3 + 7/12) ÷ (5/6 – 2/5)

= 3/10 of (4 + 7/12) ÷ (25 – 12/30)

= 3/10 of (11/12 ÷ 13/30)

= 3/10 of (11/12 ÷ 30/13)

= 3/10 of 55/26

= 3/10 of 55/26

= 33/52

(e) (1/2 – 1/3) of (2/3 – 3/5) × (4/5 – 7/15)

= 93 – 2/6) of (10 – 9/15) × (12 – 7/15)

= 7/15 × 25/4 + 5/10

= 35/12 + 5/10

= 175 + 30/60

= 205/60

= 41/12

(g) 9 1/2 – [7 1/2 + {4 – (5 – 2)}]

= 19/2 – [15/2 + {4 – 95 – 2)}]

= 19/2 – 15/2 + 1

= 19/2 – [15/2 + 1

= 19/2 – [15 + 2/2]

= 19/2 – 17/2

= 19 – 17/2

= 2/2

= 1

(h) (2/5 + 1/7) ÷ (1/5 – 1/8) – 5/21

= (14 + 5/35) ÷ (98 – 5/40) – 5/21

= 19/35 ÷ 3/40- 5/21

= 152/21 – 5/21

= 33/2 × 1/4

= 33/8

= 4 1/8 m

Question no – (2)

Solution :

Cost of 1 kg rice = 150 ÷ 3 3/4

= 150 ÷ 15/4

= 150 × 4/5

= 40 Rs

Question no – (3)

Solution :

Packets = (10 kg ÷ 1 1/4)

= (10 ÷ 5/4)

= (10 × 4/5)

= 8 packets

Question no – (4)

Solution :

Total pieces = (15 ÷ 3/4)

= 15 × 4/3

= 20 pieces

Question no – (5)

Solution :

Number, be x

= 1/5 × x = 132

= x = 132 × 5

= 660

Question no – (6)

Solution :

Girls = (40 × 3/5)

= 24

Boys = (1 – 3/5)

= 5 – 3/5

= 2/5

Question no – (7)

Solution :

= 2/13 pairs copper

Gold = (1 – 2/13) parts

= (13 – 2/13)

= 11/13 parts

∴ Weight of gold = (65 × 11/13)

= 53 gm

Question no – (8)

Solution :

Son + Daughter = (1/3 + 1/5)

= 5 + 3/15

= 8/15

Rest = (1 – 8/15)

= 7/15

Question no – (9)

Solution :

Total travel by bus and scooter,

=  (5/16 + 7/20)

= 25 + 28/80

= 53/80

Running, = (1 – 53/80)

= 80 – 53/80

= 27/80

27/80 =  540

=  27 =  540 × 80/27

= 1600 m

Therefore, altogether he will go 1600 m.

Question no – (10)

Solution :

Let, the capacity = x

= 3/4x – 12 = 5/12x

= 3/4x – 5/12x =  12

=  9x – 5x/12 =  12

=  4x =  12 × 12

= x = 12 × 12/4

= x =  36 litre

Therefore,  the capacity of the can will be 36 litre.

Question no – (11)

Solution :

Broken eggs = (52 × 6/13)

=  24 eggs.

Left = (52 – 24)

=  28 eggs

Thus, there are 24 eggs are left.

Question no – (12)

Solution :

Bharat covered = ( 1 – 2/5)

= 5 – 2/5

= 3/5th

Let, total length =  1

3/5th journey = 210

= 3 = 210 × 5

=  1 = 210 × 5/3

= 350 km

Therefore, the total length of Bharat journey was 350 km.
