Question

A two-digit number ‘P’ is 160% of another two-digit number ‘Q’, which is 160% of another two-digit number ‘R’. What is the sum of the numbers P, Q and R?​

Answer 1

Answer:

129

step by step explanation:

let the two digit number R be 'x'

R:Q:P = x:160% of x :160% of 160% of x

= x : 1.6x : 2.56x = 1 : 1.6 : 2.56

= 100 : 160 : 256

= 25 : 40 : 64

so the possible maximum sum of such two digit numbers P,Q & R will be

= 25 + 40 + 64 = 129

option(1) will be correct from the picture I provided there .
