Answer:
0.332
Step-by-step explanation:
given series
1/4, 1/16,1/64.1/256
this is geometric series
where common ratio r is given by
nth term/ (n-1)th term
let the second term is nth term and first term is (n-1)th term
r = 1/16 / (1/4) = 1/4
___________________________________________
sum of series is given by
a (1-r^n)/1-r
where a is first term
n is the number of terms
r is the common ration
___________________________________________
in the given series
1/4, 1/16,1/64.1/256
a = 1/4
r = 1/4
n = 4
thus ,
sum = 1/4(1-(1/4)^4)/ (1-1/4)
sum = 1/4(1-(1/256)/(4-1)/4
sum = 1/4((256-1)/256 / 3/4
1/4 in numerator and denominator gets cancelled
sum =( 255/256*3) = 255/768 = 0.332
Thus, sum of series is 0.332.

Step-by-step explanation:
A = x b = y c = z = 41 °
4 CAKES TOTAL £1 THEREFORE 2 CAKES COST 50p. ONE OF THE CAKES COST 10p MORE THAN THE OTHER ( 50p - 10p = 40p / 2 = 20p ) ONE CAKE COSTS 20p AND THE OTHER COSTS 30p ( 20p * 30p * 2 = £1 )
