= 7/15 ÷ 4/25 + 5/10
= 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

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.
