We know that , Pt $$=$$ $$Pc1+$$μ$$22$$ ∴ it $$=$$ $$ic1+$$μ$$22$$ ⇒ ic $$=$$  $$it1+$$μ$$22$$ $$=1.51+(0.6)22$$ $$=1.51.18$$  Now, when two signals are superimposed, then , effective modulation index μ$$2$$ $$=$$ μ$$12$$ $$+$$  μ$$22$$ $$=$$ $$(0.6)2$$ $$+$$ $$(0.7)2$$ $$=$$ $$0.85$$  So, it $$=$$ $$ic1+$$μ$$22$$ $$=$$ $$=1.51.181+0.852$$ $$=$$ $$1.64$$ A
