**4. For a sand sample 20% retained on each of #16, #30, #40 and #50 and rest 20% retain on #100 and #200 sieve equally. Find FM of this sample.**

**5. The difference between the maximum and minimum void ratio is 0.3 and field void ratio is 0.4. If relative density is 66.6% then find out the saturated density at its loosest condition. Specific gravity of the soil sample is 2.65**
