Q. If 0.75:x::5:8, Then find x
Answer: 1.2
Notes: we know that :- Product of means = Product of extremes Thus, a:b::c:d<=>$latex \left ( b\times c \right )=\left ( a\times d \right )$ So in this question we can write: $latex 5\times x=8\times 0.75$ $latex \therefore 5x=6$ $latex => x=\frac{6}{5}=1.2&s=2$
