Bags of sugar come in 3 sizes: Small bag: A 250 g bag costs 60p.
Medium bag: A 500 g bag costs £1.30.
Large bag: A 3 kg bag costs £7.50.

Small bag: £7.20 for 3 kg

Medium bag: £7.80 for 3 kg

Best value: small bag

Step-by-step explanation:

3 kg = 3000 g

Small bag: 60p/250 g = 0.24p/g

For 3000 g: 0.24p/g * 3000 g = £7.20

Medium bag: £1.30/500 g = 0.0026 £/g

For 3000 g: 0.0026 £/g * 3000 g = £7.80

Large bag:

For 3000 g: £7.50

Best value: small bag

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
