Answer»

Correct choice is (b) 1:3

Explanation: In flagstone FLOORING, while laying the slabs a string is stretched between two CORNER slabs. Other slabs are then laid in such a way that their TOPS touch this string. If a particular slab falls below the string level, then it is re-laid with the help of a fresh layer of mortar. The mortar used in flagstone flooring has cement and SAND in the ratio 1:3.
