= (324.15 + 88.45)

= Rs 412.60

Question no – (2)

Solution :

Her spent

= (88.45 + 32.70)

= Rs 121.15

Now she left

= (150 – 121.15)

= Rs 28.85

Question no – (6)

Solution :

Geetanjali is shortly

1.59

.94
————————-
.65 m than Jyoti.

Question no – (7)

Solution :

Average temperature now

23.2

– 2.6
————————-
20.6°C

Now,

F = 20.6 × 9/5 + 32

= 37.08 + 32

= 69.08°F

Question no – (8)

Solution :

The difference,

= (130 – 62)°F

= 68°F

So, Now = 68°F

= (68 – 32) × 5/9

= 36 × 5/9

= 20°C

Therefore, the difference will be 20°C
