    I'm facing a problem in resetting '160 decade counter to parallel inputs.
    I'm trying to get the decade counter to rest on the count of "3" to parallel input ("1"). For this I'm decoding the count "3" with the help of NAND gate and giving this low signal to LOAD'. But i'm unable to accomplish this. The counter keeps on counting from 0000->...1001->0000.

    I'hv attached my multisim ckt and pin diagram of IC74160.

    The inputs to your NAND and NOT are wrong. Instead of using QA QB QC, you're using QD QC QB.
