Answer:
1 ) 3:80
2) 125: 3
3) Suresh = 150
Anvanti = 350
4) 9cm
6cm
12 cm
5) 40:11
Step-by-step explanation:
1. length = 16 cm = 160 mm
d = 6 mm
d : length = 6 :1 60
= 3: 80
2 . length =10m = 100cm
breadth = 2.4 cm
length : breadth = 100 / 2.4
= 125 : 3
3 500 rupees
Suresh : Avanti = 3 /7
let suresh has 3 x ruppe
and Anvanti has 7 x rupee
3x +7x = 500
10 x= 500
x = 50
Suresh has 50× 3 = 150 Rupees
Anvanti has 50×7 =350 Rupees
4) 3x +2x +4x = 27
9x = 27
x= 3
1st side = 3×3 = 9 cm
2nd side = 2×3 = 6 cm
3rd side = 4×3= 12cm
5) cost of 50 g of coffee =80
cost of 1 g of coffee = 80/50 = 1.6
cost of 1 kg of tea = 440
cost of 1 g of tea = 440/1000 = 0.44
cost of 1 g of coffee : cost of 1 g of tea = 1.6 : 0.44
= 160/44
= 40:11
